Google has unveiled its own tablet called the Nexus 7 featuring its new Android (Version 4.1) operating system. This was revealed in 2012 I/O developer conference. The tablet hardware was built by Asus and will be sold at only $199.

Some of the features in the Tablet are:-
•    Android 4.1 (Jelly Bean) operating system: Android 4.1 is optimized to deliver Android's best performance and lowest touch latency, in an effortless, intuitive UI.
•    7-inch, 1280×800-resolution touchscreen
•    Quad-core Tegra 3 chipset with a 12-core graphics processor
•    8GB of storage (16GB version available for $249)
•    Front-facing camera
•    Wi-Fi, Bluetooth and NFC
•    Nine hours of HD video playback
•    Weighs 0.75 pounds

According to analysts the Nexus 7 tablet is “optimized for Google Play” – meaning it’s geared toward consuming music, movies, games, books, magazines and more. The feature-set and price tag will certainly put a whole lot of pressure on similarly-priced (but less powerful) 7-inch tablets like Amazon’s Kindle Fire and Barnes & Noble’s Nook Tablet.
The Nexus 7 tablet is available starting Wednesday in the Google Play market, and it will begin shipping in mid-July.

IBM's Sequoia has come out on top on the list of the world's fastest supercomputers for the US.

The newly installed system trumped Japan's K Computer made by Fujitsu which fell to second place, the BBC reported.It is the first time the US can claim pole position since it was beaten by China two years ago.

David Turek, vice president of deep computing at the firm, told the BBC his company had been preparing to retake the top spot for two years. Substantial planning went into this. We knew the day would come,” he said.

Sequoia is 1.55 times faster than the Fujitsu model, and uses over 1.5 million processors.

The Top500 list of the world’s fastest supercomputers is released every six months and compiled by Hans Meuer of the University of Mannheim in Germany, Erich Strohmaier and Horst Simon of the Lawrence Berkeley National Laboratory and Jack Dongarra of the University of Tennessee in Knoxville. The latest list was released Monday at the 2012 International Supercomputer Conference in Hamburg, Germany.

Sequoia is located at the Lawrence Livermore National Laboratory in Livermore, Calif. It was installed there in 2011 and will be fully deployed in 2012 for work on behalf of the National Nuclear Security Administration. The supercomputer was created for use by the Department of Energy’s National Nuclear Security Administration (NNSA), which was established by Congress in 2000 to manage the nation’s nuclear weapons stockpile and prevent nuclear proliferation, among other responsibilities.


China and Germany both have two supercomputers, while Japan, France and Italy have one.But IBM proved to be the leading manufacturer claiming five out of the top 10 spots.

Microsoft yesterday (18th/June/2012) unveiled its own Windows-powered tablet computer called Surface, altering its strategy of focusing on software and relying on partners to make the machines in a renewed attempt to take on Apple's iPad.
This puts Microsoft in competition with other manufacturers planning to release tablets designed for Windows 8.

The touchscreen computers will be powered by its upcoming Windows 8 system and contain a choice of an Intel or ARM-based processor.

The devices have 10.6 inch (26.9cm) displays, built-in kickstands and are housed in magnesium cases - which the microsoft described as the first of their kind. The device's cover serves as a track pad and a full keyboard.

ARM-based tablets are 9.3mm (0.4 inches) thick - slightly less than the iPad - and run the Windows RT version of the new system. The Verge reported that the chipset will be built by Nvidia.

The versions using Intel's x86 technology run Windows 8 Pro and are 13.5mm (0.5 inches) thick. The specifications mean the Surface tablets have bigger screens than the iPad but are heavier. 

The new strategy threatens to sour Microsoft's relationship with some PC makers, many of which have been investing to develop their own Windows 8 tablets and may not want to compete directly with Microsoft.

The software maker is aiming to release Windows 8 in time for the end-of-year holidays and will have a version for x86 chips from Intel and for ones based on ARM Holdings's technology, which is also used in the iPad. The Surface tablet will be available in versions running both chip designs.

Microsoft said the Surface's price will be announced closer to when the devices are available and will be "competitive with a comparable ARM tablet or Intel Ultrabook-class PC."

The world's largest software maker is stepping up its assault on the tablet market as consumers choose the devices over laptops, weakening the personal-computer market and curbing Windows revenue.

It's no secret that notebook screens are getting wider and wider. While 5:4 and 4:3 used to be the conventional aspect ratios in the past, nowadays all we see is 16:9 and 16:10 widescreen panels. Toshiba takes things even further with its new U845W Ultrabook. The laptop has a 14.4" screen with a 21:9 aspect ratio. The screen has a 1792x768 pixel resolution, making the pixel density similar to that of a 1600x900 panel of equal size.

The U845W is part of Toshiba's new 14" Satellite Ultrabook series. These devices are powered by Intel's Ivy Bridge processors, use SSDs for storage and have illuminated keyboards. The laptop doesn't have a numeric keypad, which, given the width of the device, would have been a nice addition. The battery should last around 7.5 hours. Toshiba's U845W Ultrabook weighs 1.75 kg and is about 2 cm thick. Connectivity includes three USB 3.0 connectors, HDMI and ethernet.
