The tiny Chill Innovation KB-1BT Bluetooth Micro Keyboard is 155mm x 61mm x 12mm (6.1" x 2.4" x 0.5") so you obviously can't expect full sized keys especially with the 31mm2 (1.2"2) trackpad on the side. What you can expect is to hook up the keyboard wirelessly to any device that can manage Bluetooth, the USB connection is to recharge the keyboard. MektuMods enjoyed using the device but question its value, the model they reviewed was 70 Euros (~$100USD) to purchase.
"There are several keyboard/mouse bundles available these days. The new KB-1BT combines these two items into a single package. This is something that one could imagine using while watching movies via HTPC or writing a document with an iPad. So, is it worth your money? Let us find out..."

Tagged: mobile, low power, panel self refresh
The idea behind Panel Self Refresh is a sound one, when displaying static images there is no need for the GPU portion of your processor to be refreshing it at full speed. If you simply leave the displayed image in the frame buffer you can turn off the GPU and get significant power savings. It will not help when you are streaming media but if you are reading emails or a pdf file or even browsing pictures, you should see some extension to the life of your battery. Hardware Secrets describes the technology in their article here.
"Manufacturers are always looking for innovative ways to save battery life on laptops. With the embedded DisplayPort 1.3 interface (eDP 1.3), VESA, the Video Standards Association behind DisplayPort, came up with a new idea, the Panel Self Refresh (PSR). Let's see how it works."

AMD today announced three new Accelerated Processing Units (APU) to bolster up the mobile lineup. Specifically, two new E-Series and one new C-Series APU are inserting themselves into the lineup. The new chips bring enhanced graphic capabilities, HDMI 1.4a, and DDR3 1333 support. "Today's PC users want stunning HD graphics and accelerated performance with all-day battery life and that's what AMD Fusion APUs deliver," said Chris Cloran, vice president and general manager, Client Division, AMD.
According to MaximumPC, the new E-450 APU takes the top slot, bringing two CPU cores clocked at 1.65GHz, a Radeon HD 6320 GPU clocked at a base of 508MHz and maximum of 600MHz, and a power sipping TDP of 18 watts. The second new E-Series APU carries the same 18 watt TDP and dual CPU cores as the E-450; however, it is clocked at a lower 1.3GHz. Further, the chip’s Radeon HD 6310 GPU is clocked at 488MHz. The new E-Series APUs feature battery life increases to the tune of up to 10.5 hours of Windows idle time.
The new C-Series APU is the C-60, and is a 1GHz dual core chip with a Radeon HD 6290 GPU. The APU is able to turbo its CPU cores to a maximum of 1.33GHz, while the GPU has a base clock of 276MHz and a maximum clock speed of 400MHz. Further, the chip has a 9 watt TDP, and boasts 12.25 hours of “resting battery life,” which AMD benchmarked using Windows Idle on a C-60 based netbook.
Currently, AMD has shipped more than 12 million APUs, and more than five million of the C-Series and E-Series processors in Q2 2011. More information on the specific benchmarking metrics AMD used can be found here.
It seems as though T-Mobile users’ streak of bad luck just keeps on coming. According to AllThingsD, the US cellular provider is changing its lowest tier 200MB data plan’s overage policy from throttling to overage charges. Specifically, once users exceed their allotted data, they will be charged $0.10 per megabyte, which is the bad news. The slightly better (but still not quite good) news is that the overage charges will be capped at a maximum of $30.
T-Mobile stated that it will begin notifying customers once they reach 90% of the 200MB data allotment, or 180MB, in addition to giving customers the ability to move to a higher tier data plan with a larger data allotment.
The changes in their data plan from customers being throttled to a lower data speed after going over their data allotment to being charged overage fees will happen tonight at midnight, so (new) customers who wish to become grandfathered into the plan should sign up quickly.
What are your thoughts on carrier data caps? Do you believe overage charges are the answer? Share your opinions in the comments below!

According to Ars Technica, researchers at UCLA announced on Tuesday a new LCD screen containing photovoltaic cells that promises to reduce back-light energy waste and improve battery life on mobile devices.
My N900 eats up battery with an hour of Angry Birds, but can go for two days with the display off. Where's my happy medium?
The researchers have placed what they are calling polarizing organic photovoltaics inside the LCDs in such a way that light that is normally filtered out and blocked in areas to create the displayed images can now be (mostly) recovered. While the process does not result in 100% reclamation of energy due to energy loss during the conversion process(es) and heat given off by the back-light, in a mobile device any amount of energy that can be recovered is desirable. Ars Technica states that up to 90% of a battery’s power is used to power the back-light of the display. Further, of that percentage, up to 75% is lost to the polarizing layers. By infusing the polarizing layer with photovoltaic cells and reclaiming as much of the otherwise wasted light as possible, battery life could be dramatically extended.
Mobile devices are getting beefier multi-core processors and graphics chips, numerous wireless radio connections (4G, WiFi, Bluetooth), and large power hungry displays; however, battery technology advancements have been rather stagnant and flat. As a result of this, having to make processors, displays, and other components as efficient as possible to make up the difference of battery technology not keeping up with other advancements, interesting tweaks like the photovoltaic infused displays become that much more important.
Whether this particular technology will catch on and work as well as they claim remains to be seen; however it is nonetheless an interesting experiment. More data on the researchers’ project will be published in the Advanced Materials journal in September 2011. What are your thoughts on the idea?
Samsung recently announced volume production of a new lineup of SSDs using the fast SATA 3 (6Gb/s) interface and will be available in 128GB, 256GB, and 512GB capacities. The new SSDs are called the PM830 series, and Samsung expects the drives to replace their SATA 2 (3Gb/s) drives by year-end.
Wanhoon Hong, executive vice president, memory sales & marketing, Device Solutions, Samsung Electronics stated that Samsung's new SSDs "will raise the performance bar to the next level for ultra-slim notebooks and tablets." In addition, he believes that the new high capacity drives will spur competition in that segment and increase market interest in SSDs with greater-than 256GB capacities.
The new PM830 drives use Samsung's 20nm class (their term for a process node somewhere between 20 and 29), 32 Gigabit MLC NAND flash with a toggle DDR interface in addition to a proprietary controller. Samsung claims that the controller and flash are able to take advantage of the SATA 6Gb/s interface by delivering 500MB/s sequential read speeds and 350MB/s sequential write speeds. Further, the drive uses AES 256-bit encryption to secure private and corporate data.
The new SATA 6Gb/s solid state drives are targeted at OEMs for use in notebooks and tablets. They are currently only available to OEMs; however, a consumer variant of the drive is forthcoming and will be announced at a later date.

Mobile gaming has seen a relatively sharp rise in popularity in recent years thanks to the rise of powerful smartphones and personal media players like the iPod Touch and its accompanying App Store. Mobile networks, powerful System On A Chips (SoC) that are capable of 3D graphics, lighting, and physics, and a large catalog of easy to download and play games have created an environment where people actually want to play games on their mobile devices. Many people now indulge themselves in quick Angry Birds sessions while in long lines, on work breaks, or wherever they have time when out and about.
One area where mobile devices have not caught on; however, is at home. Mobile devices face stiff competition from game consoles and the PC. That competition has not stopped numerous manufacturers from trying to implement an all-in-one mobile console that was portable and easy to plug into a larger display when at home. Everything from cheap controllers with logic inside that allows them to play old arcade games to smart phones with HDMI outputs costing hundreds of dollars have passed through the hands of consumers; however, the mobile console has yet to overcome the sheer mind share of consumers who prefer dedicated game consoles and their PCs.
According to Anandtech, Qualcomm, a popular manufacturer of ARM SoC for smart phones has announced its plans to pursue that vision of an integrated, mobile console. They claim that the increased power provided by next generation SoC technology will allow tablets and smartphones to deliver graphics that are better than those of current dedicated game consoles like the PS3 and Xbox 360. Due to Sony and Microsoft wanting to extend the lives of consoles well into the future, mobile technology may well surpass it. The company "is committed to delivering both the hardware and the software support needed to bring developers to these mobile platforms," according to Anandtech.
Qualcomm wants to bring portable consoles to the masses powered by their SoCs and backed by their software. The tablets and smartphones would be able to connect to displays using HDMI or wireless technology in addition to supporting controllers (or acting as a controller itself). Further, the games library will be the culmination of software from all platforms and will rival the graphical prowess of the current consoles. Qualcomm hopes that a large library and capable hardware will be enough to entice consumers to the idea of a portable console becoming their all-in-one gaming device.
Portable consoles are similar to tablets and 3D television in that there is a major push for it every few years, a few devices come out, and then it dies off to be reborn again a few years later. Whether Qualcomm is able to pull off the plans for a portable console remains to be seen; however, the device is bound to catch on at some point. At the very least, this is certainly not the last time we will hear about the portable console. You can see more of Qualcomms plans here.
What do you believe is holding back the portable console from catching on with consumers? Is it a good idea in the first place?
With Google reporting daily Android device activations upward of 550,000 devices a day, the rapid growth and ubiqutity of the platform cannot be denied. As the platform has grown, we here at PC Perspective have constantly kept our eye out for ways to assess and compare the performance of different devices running the same mobile operating systems. In the past we have done performance testing with applications such as Quadrant and Linpack, and GPU testing with NenaMark and Qualcomm's NeoCore product.
Today we are taking a look at a new mobile benchmark from Qualcomm, named Vellamo. Qualcomm has seen the need for an agnostic browser benchmark on Android, and so came Vellamo. A video introduction from Qualcomm's Director of Product Management, Sy Choudhury, is below.

Gateway recently unveiled two new updated notebooks from their ID and NV series. Featuring HDMI, USB 3.0, LED backlit displays, and powered by Intel Sandy Bridge (2nd generation Core) processors, the ID47 and NV57 (and NV55) notebooks bring a welcome refresh to their lineup. The updated notebooks further feature 802.11 b/g/n WiFi, a 1.3MP webcam, and battery lives of 8 hours for the ID series and 4 hours for the NV notebooks.
An interesting addition to the traditional laptop layout of speakers, keyboard, and touchpad is a number of hot keys that launch social widgets to access the various social networks including Facebook, YouTube, and Flickr. Users are then able to post updates and upload images and videos in addition to viewing the social network’s feeds.
The ID47 notebook with brushed metal design
The Gateway ID47 is a traditional 13” chassis that holds a 14” LED backlit HD display with full edge to edge glass. The chassis itself comes into two designs, either an “Infinity Blue” or a “Brushed Platinum” look that Gateway claims resembles tranquil water and an industrial look respectively. Regardless of which design one chooses, the top right of the aluminum notebook lid features a stainless steel laser-engraved logo.
Further, a revamped keyboard, 20% larger trackpad, integrated DVD drive, and a mesh speaker bar. The notebook’s full dimensions are 12.97 (width) x 8.95 (depth) x .85 to 1.13 (height) inches. Gateway claims that the notebook is comfortable to carry and easily portable.
In Canada, certain ID series notebook models will be available with a 15.6 in HD widescreen LED backlit displays, and will be further powered by NVIDIA GeForce GT graphics and will use NVIDIA Optimus switchable graphics technology.
On the other hand, the NV series is a 15.6” form factor, and has a 15.6” HD LED backlit display. The new notebooks also come in two design flavors, including a geometric pattern or a digital wave pattern on the matte chassis lid. The chassis further features a chiclet keyboard and geometric or digital wave pattern on the palm rest. The NV series is then further broken up, into the NV57 and NV55 series. The NV57 notebooks are powered by Intel Sandy Bridge processors and Intel HD Graphics 3000 with 128 MB of dedicated system memory for the processor-integrated GPU. In contrast, the NV55 laptops are powered by AMD A series processors.
The ID and NV series are available for purchase now at retailers around the US and Canada with a MSRP starting at $699.99 US and $799.00 CAD for the ID series and $529.99 US and $499.00 CAD. On the bundled software side of things, the notebooks come with Windows 7 Home Premium, a backup program called MyBackup, in addition to “useful extras including Nook for PC, Adobe Flash Player 10.1, Adobe Reader, WildTangent Demo Games, Skype, Norton Online Backup, and Microsoft® Office 2010 (preloaded for online purchase).”
NVIDIA recently unveiled a new four core CPU for mobile devices at Mobile World Congress which promises to power 2560x1600, 300 DPI displays as well as enable realistic dynamic lighting and physics in mobile games, features that until recently were only possible in the realm of gaming laptops and desktops.
The quad core ARM CPU has been paired with a new 12 core GeForce graphics processing unit. The CPU alone is able to outperform the older Tegra 2 chip by close to 2x. With the additional GPU cores; however, NVIDIA has even more performance, and the ability to implement great looking games for mobile tablets and so called “super phones.”
At a resolution of 1280x800 (according to Engadget), the new Kal-El graphics demo shows off a new game featuring a glowing ball that acts as a truly dynamic light source in addition to realistic cloth physics. Using all four processing cores of the CPU allowed NVIDIA to implement cloth that reacts to the changing gravity of the game in a dynamic- and very realistic looking- manner. The mobile chip saw approximately 80% usage across all cores during the game demo. When NVIDIA disabled two of the CPU cores, the game became nearly unplayable, with the two remaining cores maxed out, the demo’s frame rate dropped to below 15 frames per second.
The new “Tegra Super Chip” will certainly allow mobile game developers to design immersive and realistic looking worlds as well as enhancing consumers’ ability to watch 1080p HD video with ease. The only drawback of the chip seems to be that battery technology is much slower to advance than transistor technology; therefore, it will be interesting to see how the new NVIDIA chip performs in that regard.
