Logitech Tablet Bluetooth Keyboard for Android 3.0+

                    Logitech Tablet Keyboard for Android 3.0+

Logitech's Tablet Keyboard for Android 3.0+ packs in plenty of bang for your buck. In addition to a superb keyboard, the product comes with a protective case that doubles as a stand for your tablet, allowing you to position the device vertically while you type. This all-in-one functionality adds a lot of value to the Logitech unit.

Of course, the most important thing is the keyboard itself -- and Logitech's creation is no slouch in that regard. The keys are nicely spaced out and very responsive; I found it comfortable to perform even the fastest of typing. The unit lies more or less flat when placed on a table, with an ever-so-slight upward slant.
The Logitech Tablet Keyboard has five rows; the number keys at the top double as Android function keys when used in conjunction with a function (Fn) button. Those Android keys allow you to open your tablet's browser, music player, calendar, or Gmail app, as well as remotely control music playback and volume on the tablet. These are handy, but I would have liked it better if they had been dedicated rather than combination keys. The keyboard does have dedicated Search, Back, Home and Menu keys.

Have an iPad?

If you want a wireless keyboard for your iPad, try "Hands-on: 5 wireless keyboards for the iPad."
Though all of the keyboards I tested offer Delete keys, the Logitech keyboard is the only one on which the key actually functions as you would expect: It deletes the letter that comes immediately after the cursor. For some reason, every other keyboard's Delete key either did nothing or served as a second Backspace key, deleting letters before the cursor instead of after it.

Bluetooth keyboards for Android tablets

If you need a real keyboard to do real work, here are three excellent and affordable options

 Tablets give us new possibilities when it comes to mobile computing. Unfortunately, they also give us new things to pack when it comes to carry-on luggage.
The problem is simple: While a tablet is a great addition to any gadget-lover's arsenal, it isn't typically a replacement for an existing device. Most of us still need physical keyboards for long-form typing -- and with business travel in particular, that means you're lugging around both a tablet and a laptop.

3 Android keyboards

  • Introduction
  • Logitech Tablet Keyboard for Android 3.0+
  • Motorola Wireless Keyboard
  • Targus Bluetooth Wireless Keyboard for Tablets
  • Bottom line
By adding a wireless keyboard to your tablet, though, you can transform it from a content-consuming slate into a far more versatile productivity machine. With the aid of a Bluetooth keyboard, I've been able to use my Motorola Xoom for all of my computing needs -- both work and personal -- while away from the office. The keyboard allows me to type desktop-style as needed; the rest of the time, I can use the tablet as a lightweight touch device.When it comes to keyboards, Android tablets do have a disadvantage: Because the tablets come in a variety of sizes and formats, keyboard manufacturers tend not to create the convenient combination keyboards/cases that are available for the iPad. However, there are still some really excellent options out there.

Top 10 Mobile Applications of 2012

For many of the categories on this list, there are a number of mobile apps that are already available today. But what Gartner makes clear is that we're just getting started when it comes to their use.
For example, location-based services (LBS) - there still isn't one single app which everyone uses to find their friends out in the real world via their mobile phones. Instead, we have a number of similar but competing applications all vying to be the Facebook of location-based apps.
Another example is money payments - this type of service is having more of an impact in the developing world right now where access to banks is more difficult than here in the Western world where people just want the convenience of paying through their mobiles. When was the last time you paid someone or paid at checkout through your mobile phone? Never? That sounds about right.
The List

The full list is as follows:
Money Transfer: This refers to people sending money via SMS messages. Like mobile payments, this service has more appeal in developing markets for now. However, there may come a time when even using your debit card seems passé, while paying for something with actual cash seems downright ancient.
Location-Based Services: As mentioned above, there are still far too many services to choose from when it comes to location-based social networking, fragmenting the market. Your friends on Loopt are often different than those on Brightkite and that list is different than those on Foursquare. But LBS extends to more than social networks - it includes any application that taps into your phone's GPS capabilities to offer up location-based services of any kind, whether that's local business reviews or directions to the nearest Starbucks. Gartner says this will be one of the most disruptive technologies in the future, with a user base growing from 96 million in 2009 to 526 million in 2012.
Mobile Search: No, mobile search isn't new, but on the mobile platform, it may get shaken up a bit. Gartner predicts that consumers won't necessarily be sticking with the search services they know and use on the Web (think Google, Bing, Yahoo) and instead experiment with using a few different search providers that have "unique technologies" for mobile search. While that statement is a little vague, it sounds like good news for services like Taptu who have entered this field with search offerings designed from the ground-up for mobile devices.

Mobile Browsing: Saying that mobile browsing technologies will be heavily used in the future sounds a little bit like stating the obvious. But as Gartner notes, mobile browsing capabilities currently exist only on 60%+ of handsets today. By 2013, that number will climb to 80%, meaning that those who are still using the app-less,more basic feature phones will still be joining the mobile web in mass numbers over the coming years. That's also good news for web developers who can build mobile web applications to cater to this bunch as opposed to focusing all their efforts into building apps for the numerous mobile platforms like the iPhone, Android, RIM, and others.
Mobile Health Monitoring: Another technology whose impact will be felt more heavily in developing markets, mobile health monitoring is still at an early stage of maturity and implementation says Gartner. Project rollouts have been limited to pilot projects for now, but in the coming years the industry will begin to monetize these efforts by offering mobile healthcare monitoring products, services, and solutions to various care delivery organizations.
Mobile Payments: Like mobile transfers, mobile payments are more common in developing markets at the moment, but that is quickly changing. Yet even as this type of service grows, Gartner admits there will be challenges. Mobile payments will be a "highly fragmented market" where there will not be "standard practices of deployment," notes the report. That makes it sound like this is one technology that will still need some work, even when 2012 rolls around.
Near Field Communications (NFC): More popular in some European and Asian markets than in the U.S., NFC still isn't a standard feature on many of today's phones. That may be about to change, too. In late 2010, Gartner says that NFC-enabled phones will begin to ship in volume, with Asia leading deployments, followed by Europe and North America.
Mobile Advertising: Also not new but growing fast, mobile advertising is one of the most important ways to monetize mobile content. Total spending on mobile advertising in 2008 was $530.2 million and it will grow to $7.5 billion in 2012. And mobile advertising will also be used by companies alongside their other campaigns including TV, radio, print, and outdoors.
Mobile Instant Messaging: Gartner says that latent user demand and market conditions are conductive to mobile IM's future adoption. It will appeal to developing markets where mobile phones are often the only connectivity device a user owns. But will it be a major app by 2012? It seems that SMS is still the service to beat, especially in the developing world. We'll have to wait and see on this one.
Mobile Music: Sure, you have the iPhone, but what about your other options? What about mobile music services - especially those for non-iPhone devices? We're still waiting on Spotifyin the U.S., for example, and their competition too. Gartner says that we're beginning to see new innovative models in this area that will include both device (think "Comes with Music") and service bundles.

Research firm Gartner has just put out a list of the top ten mobile applications of the future. Well, not the distant future, but the far off year of 2012. Nothing on the list is all that surprising or, in many cases, even all that new. Instead, the list includes the sorts of technologies that are just now coming into their own and haven't yet seen widespread adoption as well as the already common technologies that are still experiencing growth.
What's Missing?

A glaring omission from this report is that of Augmented Reality. Gartner had even placed this technology on their "Hype Cycle for Emerging Technologies, 2009" report earlier this year. Do they not think that AR will have a major impact by 2012? Considering that's only a little over a year away, it could just be too soon for AR to see the widespread adoption that we hoped it would have by then. Or it's possible that - as some have suspected - AR is simply a "cool" way to see and interact with the world around you, but hasn't produced any "must-have," highly useful applications just yet. For example, seeing AR views of local businesses and user recommendations is fun, but is it a markedly better experience than using a service like Yelp? For many, that answer today is "no." AR needs to grow out of being a technology you use "because you can" to one you use "because you have to." Until it's the best option to perform a particular task, it may not make Gartner's next list, either.

India’s cheapest Android tablet

Akash Ubislate, India’s cheapest Android tablet launched

The much anticipated $35 tablet has been officially launched by Union Ministry for Human Resource Development. The tablet is called Akash Ubislate and will be available to students at the subsidized price of $35 (approx Rs. 1720).




Weighing 350 grams, Akash tablet features a 7 inch resistive touchscreen diaplay, has 256 MB RAM, 2 GB internal storage, 32 GB expandable memory slot, two USB ports, Wi-Fi IEEE 802.11 b/g connectivity and 3.5 mm audio jack.

Akash Ubislate is powered by Android 2.2 OS and 366 Mhz. Connexant with Graphics accelerator and HD Video processor. Premium version of this tablet will also have inbuilt cellular modem (GSM/3G) and SIM card slot.

Windows 8 smartphone

A Chinese company says it will bring the yet-to-be-released Windows 8 to the small screen.

In Technology Group has seemingly dedicated itself to merging the Windows PC experience with the smartphone--something the company has dubbed the "post-smartphone." They started with phones running Windows XP a few years ago, and by earlier this year, ITG's XPPhone was available with Windows 7. Now it says a far slimmer, lighter, and energy efficient XPPhone 2 that will run both Windows 7 and the PC version of Windows 8 (once it's released) is in the works.

Though it seems doubtful to me that many consumers will find a need for so much Windows in their pocket, ITG has made sure to pack the XPPhone 2 with the meaty hardware to pull it off. This beast will boast a 1.6GHz processor and 2GB of RAM. ITG's Web site also mentions the possibility of an insane 2GHz model. There's also plenty of storage space to house Microsoft's notoriously bulky OSes, with 112GB on board.

ITG is billing the XPPhone 2 not just as a phone but as the "smallest notebook PC in the world," measuring 140mm X 73mm X 17.5mm. The pitch is basically that the phone is easily dockable and can stand in for a laptop, desktop and in-car navigation system.

The success of this kind of a device will likely depend on it being at least more usable than the English translation of its press release, which requires several aspirin to navigate, with sentences like: "The Editor considers that, presently it forms three camps of smart phone in the way of tripartite confrontation--The Apple, Google & Moto, and Intel & Microsoft & xpPhone, of which stands for three complete different technical orientations."

Let's hope they took the money they saved on their translator and put it into engineering.Engadget reports that we could see an XPPhone 2 release as soon as January.

Cisco is going to change the internet forever

Cisco has been claiming they will "change the internet forever" and their impact on individuals, governments, and businesses will be revolutionary. While Cisco is making these claims, what exactly are they doing that is so monumental that it will change the internet and the way in which we browse online?


Cisco announced a new networking router that is going to be top-of-the-line and transform the internet. This revolutionary product is known as the Cisco CRS-3 Routing System. This new router is setting the standard for all future growth of the internet, especially for video growth to occur. It has about 12 times more traffic capacity from other systems. It transfers about 322 terabits per second, which is absolutely amazing compared to other systems.

How fast is it really? Well according to Cisco you can download the entire Library of Congress in about a second. Pretty impressive right? The internet is going to keep growing and advancing and users are demanding faster service, better download capabilities, and better online browsing. It looks as though Cisco is listening to these demands and they are trying to meet the expectations of customers.

Current and Upcoming Tablets ipod


The tablet market is like that kid in school who, at first, no one really noticed. Then, a year later he starts the school year a foot taller, with a new wardrobe, and suddenly everyone wants to be his friend. But, does he deserve his newfound popularity?


I really don't know. Personally, I've yet to purchase a tablet, and I've still not seen a compelling reason to do so. Still, millions feel differently and have already dived full on into the tablet sector.

Yet, every day there seems to be a new announcement of another manufacturer's plans to release a tablet. Today is no different, with the announcement of the iPad 2. It's getting confusing and a little crazy out there, and we at CNET wanted to provide you with a snapshot of not only the current tablet landscape, but a look into the near future and how it's evolving.

We've compiled a list of all the major current tablets interwoven with all the tablets yet to be released. This list will focus on non-Windows tablets only for now. Enjoy, and if there's any other information you'd like to see on this list, let us know in the comments or via e-mail.

Look for this post to be updated and evolve throughout the coming months.

Apple targeted by Samsung, S3 in new suits


Apple this week is once again the target of new lawsuits from companies with which it's already entangled in separate legal battles.

The first salvo comes from Samsung. Bloomberg reports that Samsung filed four suits against the company this week, with the first related hearing in the cases to kick off early next week.

A court representative did not tell the news outlet what the Netherlands suits were about, though Samsung has taken aim at Apple in the U.S., Europe, and other countries for allegedly infringing on its patents, with lawsuits targeting the tech giant's portable devices.

Separately, S3 Graphics filed a suit yesterday against Apple for allegedly infringing on two of its patents covering 3D rendering and VGA controller circuitry. Both patents were issued in the 1990s. The suit, filed in the U.S. District Court in Delaware, takes aim specifically at Apple's iPhone, iPad, and iPod Touch, along with Apple's desktop and notebook computers, as infringing.

The new S3 suit is of special note given that the two companies had previously been engaged in a legal spat with the U.S. International Trade Commission. That led to the government group issuing a partial ruling against Apple, saying that Mac OS X was violating S3's patents. HTC, which sued Apple in separate suits earlier this month and last month, announced plans to buy S3 from Via Technologies in July.

mLearning and the Global Classroom


Adults and adolescents with Atopic Dermatitis in the USA, expectant mothers in Ghana, young teachers in Finland and pharmacists in Uganda all have one thing in common, they are part of the growing mobile learning community, or mLearning.  Educators use cell phones, PDAs, laptops, and other mobile devices to reach students who are mobile, are isolated, lack internet access, or have limited resources for travel but have a mobile phone.  mLearning in action.  When 90% of the world’s population has access to a mobile phone, according to the International Telecommunication Union, it is no surprise that educators have already realized the potential of mobile devices to enhance and extend the classroom.

Facebook builds tighter integration with music, TV

Facebook unveiled new ways for users to listen to music and watch TV, offering tie-ups with the likes of Spotify and Hulu, as it attempts to make media an integral part of its social networking service.


The features, which Facebook unveiled at its annual f8 developers' conference in San Francisco on Thursday, will vastly expand the types of activities that users of the social networking service can notify their friends about, from the news articles they read to the title of each song they listen to throughout the day.

 Facebook users will also be able to listen along to whatever song a friend is listening to, provided they both subscribe to the supported third-party streaming music services, such as Spotify.

 The media push comes as Facebook faces fresh competition from Google, which in June launched a rival social networking service, Google+. In recent weeks, Facebook, which counts more than 750 million users, has rolled out a bevy of changes to its service.

 "Facebook is positioning itself as not just your social graph online, but your life online," said Forrester Research analyst Sean Corcoran.

 "These changes not only help trump rival Google but will open up new opportunities," he said. "But concerns around privacy and immaturity in how to do these things effectively will make it a slow go."

 Dressed in a gray T-shirt, jeans and sneakers, Zuckerberg said the music companies partnering with Facebook, including Rhapsody and Turntable.fm, were reinventing the music industry and the business models that underlie the industry.

 "They believe that the key to making the music business work isn't trying to block you from listening to songs you haven't bought," said Zuckerberg.

 "It's trying to help you discover so many songs that you end up buying even more content than you ever would have otherwise," he said.

 Joining Zuckerberg on stage was Netflix Chief Executive and Facebook board member Reed Hastings, who said he was excited to offer tighter integration with Facebook but did not give details.

 The Washington Post Co. unveiled its Social Reader, which lets people read and share stories from the newspaper within Facebook.

 For Facebook, a deeper integration of music, movies and other media into its service makes it more likely that users will spend more time on its site, enabling the company to generate more advertising dollars.

 The company, which generated $1.6 billion in revenue in the first six months of 2011 according to a source familiar with the matter, is being closely watched by investors hoping for an initial public stock offering next year.

 Facebook also introduced an overhaul of users' personal profiles on Thursday which arranges past photos and other information into a rich, magazine-like layout. Dubbed "Timeline," the new profile serves as a sort of diary of a person's life, organized by each year they've been on Facebook.

 With Thursday's new features, Facebook users will have new ways to flag content beyond the now familiar "like" button which people click to endorse various items on the Web, from news articles to running shoes.

 Software developers whose services connect with Facebook will be able to customize the types of notifications that are broadcast to a Facebook user's friends, with terms like "watched" a video, "read" an article or even "ate" a certain dish.

 All that extra information could be a boon for advertisers.

 "With Facebook now able to collect more data in terms of what people are watching, reading, running, doing, that's more metadata which is now going to feed into what brands and marketers target," said Hussein Fazal, the CEO of AdParlor, a firm that runs Facebook advertising campaigns for companies including Groupon.

Facebook Changes Again: Everything You Need To Know


Facebook  introduced some of the most profound changes seen on Facebook since its inception. So many changes, in fact, that it can be hard to keep track. So here’s a handy-dandy guide.

1. You’re going to get a Timeline — a scrapbook of your life. In a complete overhaul of its ever-evolving profile page, Facebook is introducing Timeline. This is a stream of information about you — the photos you’ve posted, all your status updates, the apps you’ve used, even the places you’ve visited on a world map — that scrolls all the way back to your birth. It encourages you to post more stuff about your past, such as baby pictures, using Facebook as a scrapbook.

The further back in Timeline you go, the more Facebook will compress the information so that you’re only seeing the most interesting parts of your history. You can customize this by clicking on a star next to a status, say, or enlarging a picture.

Timeline is in beta now, and will be opt-in to start. In the long run, it will become the new default profile page.

2. You don’t have to just Like something — now you can [verb] any [noun]. Remember when all you could do to something on Facebook — a video, a comment, a product, a person — was Like it? Pretty soon that’s going to seem laughably antiquated. The social network has launched Facebook Gestures, which means that Facebook’s partners and developers can turn any verb into a button.

So you’ll start seeing the option to tell the world you’re Reading a particular book, for example, or Watching a given movie, or Listening to a certain tune. In turn, as many observers have pointed out, this is likely to lead to an explosion of oversharing — and far more information on your friends’ activities showing up in your news feed than you probably cared to know.

How to Make Your Internet Connection Faster, Better

OpenDNS to the Internet Connection Performance Rescue


Have you ever pointed your browser to a Web site and had to wait an inordinately long time for the page — or at least the full page — to load? This kind of slow browsing experience can be traced to a variety of causes, but among the most common are problems with the servers that are responsible for actually locating all the sites you visit, your DNS (Domain Name Service) servers.

 A free service called OpenDNS can not only help your browser display Web pages faster it also offers some useful fringe benefits such as address typo correction and phishing protection, plus site blocking, content filtering and more. Before we delve into how to use OpenDNS, let's briefly outline how the DNS system works for those who may not be familiar with it.

What's the Deal with DNS?

 Every time you type a Web site address like www.practicallynetworked.com into your browser, that "friendly" address needs to be translated into the actual IP address for the computer hosting that site. The job of the DNS server is to take the text address you type in, look it up against a database of IP addresses, and then return the correct address to your browser so that the site can be accessed.

 The DNS database is actually distributed across countless servers all over the Internet, but the specific DNS server(s) you use are generally provided by your ISP. When your router obtains its IP address information from your ISP (usually through DHCP), the addresses for the DNS servers are provided as well. These DNS server addresses are in turn passed along to each of your computers via DHCP on your own network so that they all know where to go to look up Internet addresses.

 Long story short: If DNS servers get overloaded or experience other technical problems, they may take a long time to respond to lookup requests or they may not respond at all. Some ISPs are better than others when it comes to maintaining their DNS servers, but problems are not at all uncommon. Sometimes when your Internet connection seems to be down, it may be fine but simply appear down because your ISP's DNS isn't working properly.

 But you don't necessarily need to use your ISP's DNS servers, which brings us back to OpenDNS. OpenDNS, which has been around for about 18 months, is a free DNS service anyone can use, and is more than likely faster and more reliable than the one you're using now. (I've been using it for almost a year now and like many others have found the performance to be excellent.)

How to Use OpenDNS

 So how can you take advantage of OpenDNS? All you need to do is go is update your router's DNS settings via its administrator control panel. After you've logged into your router, look for settings related to DNS — the exact location will vary depending on your router, but you'll often find it under the LAN heading or sometimes even on the first settings page you see.

 When you find the DNS configuration area, you'll probably see that it's set to automatically obtain DNS servers from your ISP. Select the option that allows you to specify your own DNS server addresses, and then enter 208.67.222.222 as the primary DNS and 208.67.220.220 as the secondary DNS (as you might guess, the secondary is used if the primary isn't available).

 Your router may or may not reboot itself once you apply the new DNS settings, but in order to make sure each of your computers is using the OpenDNS servers, you should manually obtain a new DHCP address for each of them. An easy way to do this in XP is to right-click your network connection's tray icon and select Repair. In Vista, you can verify that a particular system is using OpenDNS if you see "You're using OpenDNS" message when you browse to welcome.opendns.com.)

 After some time spent using OpenDNS, you should notice that your browser generally takes less time to find and display Web sites. Even if you don't see a perceptible increase in performance, you'll still be able to benefit from several security and convenience features. For starters, OpenDNS can fix typos in the URLs you type, so if you accidentally type www.practicallynetworked.cmo — or .co, or .cm — you'll still be taken to the site you intended instead of being greeted by error message, or worse, an ersatz site from Cameroon (which owns the .cm domain).

 If you happen to type a nonexistent site name, instead of a not found error you'll see an OpenDNS Guide page with suggested alternate links (as well as some sponsored ones, which help keep OpenDNS free). For example, I sometimes inadvertently try to access the PracticallyNetworked.com site by typing in "pracnet.com" (PracNet is an internal nickname for the site), and when I do, PracticallyNetworked.com is first among the OpenDNS suggested links. Last but not least, using OpenDNS also gets you automatic phishing protection, so if the site you want to go to is known for phishing, OpenDNS won't take you there.

Windows 7: A Complete Survival Guide



Yet questions still remain about upgrading to the new OS, how Windows 7 works compared to Vista, and whether there will be any serious compatibility issues once Windows 7 is finally installed on computers across the United States.


There are a lot of questions out there about Windows 7, and I have answers. I've gone through the PC World vault to find all the information you need about upgrading, the pros and cons of buying a new system, Windows 7 security, and more. With this handy guide at your side, you'll be able to embrace everything Windows 7 has to offer.

Upgrade to Windows 7


Upgrading to a new Windows OS is always filled with questions, like which version of Windows 7 is for me? How much does it cost? Should I even bother upgrading at all?

Check out our Windows 7 Upgrade FAQ to read up on the numerous editions of the OS, and to find pricing information. But you may want to hold off on upgrading since Windows 7 upgrade fees could go down in the near future.

If you're still trying to decide whether the new OS is for you, here is why you should upgrade to Windows 7, and reasons why you shouldn't bother. We also have information about an online tool that tells you if your PC is upgrade-ready.

But if you're ready to make the switch, be sure you go through PC World's Windows 7 upgrade checklist, and the installation how-to guide. They can help ease you through the process. If you're a business owner, you should also read over these four tips for smooth upgrades to Windows 7.

Windows XP users may find the upgrade process too difficult, but we've got an XP-to-Windows 7 upgrade guide to make it easier. Netbook owners should also check out how you can get from XP to Windows 7 in just 30 minutes. But even if you decide to stick with XP, that doesn't mean you can't have some of the great new functionality in Windows 7. See how you can get Windows 7 features on an XP or Vista system.
Should I Buy a New System?


When Vista was released, it was clear that most users were going to need a new system to handle the OS. Windows 7, however, is supposedly designed to run on anything, and was even found to be a little bit faster than Vista in PC World's performance tests. So you may not need a new computer after all, but if you're running XP or finding the upgrade path a little too scary, maybe you should splurge on that new laptop you've had your eye on.

IT manager and PC World blogger Michael Scalisi has a great FAQ to help you through the big decision, but the Tech Inciter, David Coursey, says forget about upgrading and just buy a new computer already.

If you do decide to invest in a new machine, or even if you've upgraded, PC World's David Murphy has some tips to help you optimize your Windows 7 system.

Features, Features, Features


Windows 7 is loaded with new features and interface changes. Some you may find intuitive, while others are going to take some time getting used to.

4 reasons to synchronize your phone with your PC


Think about how much you do—or could do—with your phone: make phone calls and send and receive email, IM, and text messages. You probably download TV shows, movies, and music to your phone. And of course, you take, send, and receive photos. It's truly amazing—anywhere you go, you're connected. So here's the question. If you already have everything on your phone, why sync it with your PC?

Because synchronizing your phone with your PC is the best way to transfer information, settings, and files. You keep all your information up to date. And you have it at home and at work.
Keep appointments

We're all overbooked. If you've entered an appointment or meeting into your PC and haven't synced with your phone, you could miss the appointment. If you’re scheduling appointments away from home on your phone and your phone's not synced with the up-to-date schedule on your computer, you may miss the appointment and have to call the dentist, piano teacher, or doctor to reschedule. Often, you have to pay for those missed appointments. Plus, you go through the hassle of rescheduling.

Intel runs PC on CPU powered by solar cell

Intel shows an experimental chip that can run at under 10 milliwatts


Intel on Thursday showed an experimental low-power processor the size of a postage stamp that could run PCs on solar power.

The concept processor, code-named Claremont, can run light workloads on solar power by dropping energy consumption to under 10 milliwatts, said Justin Rattner, chief technology officer at Intel, during a keynote address at the Intel Developer Forum in San Francisco. That is low enough to keep a chip running on a solar cell the size of a stamp.

This CPU, also called near-threshold voltage processor, may not become a commercial product, but the research could be integrated into future processors and other circuitry, Rattner said. It is part of a project in Intel Labs to reduce energy consumption five-fold on chips and to bring always-on capability to computing devices. It also will help Intel reach goals to drop power consumption when running parallel processing applications.

The chip is an experimental Pentium CPU and ran on a PC with the Linux operating system. The CPU worked in conjunction with concept DDR3 memory developed by Micron called Hybrid Memory Cube, which is seven times more power-efficient than current DDR3 memory.

The postage-stamp chip was also demonstrated on Tuesday at Intel CEO Paul Otellini's keynote at IDF. Otellini said Intel wanted to drive down power consumption of chips, and an Intel engineer demonstrated a computer running a small animation powered by a solar panel. After the solar source -- a lamp -- was blocked from the chip, the computer froze.

Today's CPUs operate several times higher than the threshold, said Shekhar Borkar, an Intel researcher, during the on-stage demonstration. At low thresholds, the CPU dropped not only power consumption, but also performance. On full power, the CPU operated 10 times faster.

The company's goal is to deliver a 300-fold improvement in energy efficiency in high-performance computing over 10 years. To illustrate the point, Borkar said that today's servers need about 200 watts of power for 100 gigaflops of performance. The company wants to drive the power consumption down to 2 watts.

Beyond fine-grained power management and efficient memory, extreme-scale computing will require better software and programming models to achieve the goal, and Intel will continue research in those areas, Borkar said.

Intel, Google team to optimize Android for smartphones


Intel and Google announced Tuesday that they would partner to optimize future versions of the Android OS for smartphones and other mobile devices using Intel chips.
Intel CEO Paul Otellini demonstrated a smartphone with the upcoming Medfield chip running on Android during a keynote at the Intel Developer Conference being held in San Francisco. However, Otellini didn't mention the version of Android running on the smartphone.

Intel wants to make x86 the architecture of choice for smartphones, and porting Android will provide a larger opportunity to the chip maker in the smartphone market, Otellini said.

"This is a significant step forward to bring Intel phones to market," Otellini said.

Intel doesn't have a presence in the smartphone market yet, but Otellini said a smartphone based on the chip would reach the market in the first quarter next year. Medfield includes a low-power Atom processor. A smartphone with the chip was due in the third quarter this year, but has been delayed multiple times. Intel also is holding a technical session at IDF to show Medfield running on tablets.

Intel and Google will work on optimizing "all" future Android releases for Intel mobile chips at the kernel level, and also in specific areas such as memory management and graphics, said Andy Rubin, senior vice president for mobile at Google, in an on-stage appearance.
