Sony’s stylish VAIO notebooks are the cream of the crop of their computer offering and today the Japanese consumer electronics giant refreshed the S Series with better processor and graphics options and a redesigned "full flat" appearance.

The VAIO S notebooks have always been a synonym for portability due to their thinness and lightness. The new VAIO S series features a new look exterior with the casing crafted in magnesium that sports a wide aluminum palmrest and a cleverly concealed hinge mechanism, Sony said.

Internal components include an Intel Core i5-2410M processor with 4GB of 1333MHz DDR3 RAM and discreet AMD Radeon HD 6470M graphics with either 512MB or 1GB of dedicated video memory. The discreet card kicks in dynamically when the integrated Intel HD graphics isn’t enough, allowing for "balanced stamina and performance."

Other hardware features include a 13.3-inch 1366 by 768 display with 16:9 aspect ration, built-in 802.11n wireless networking, a 500GB hard drive, an optional 3G 7.2Mbps module on selected models, backlit keyboard, an USB 3 port, a webcam, and more.

The machine weighs in at 3.9 pounds (1.75kg) and its overall thickness shrinks to about 24mm. It comes preloaded with Windows 7 from Microsoft and Sony’s Fast Boot software that promises to halve the boot time. The internal lithium polymer battery is said to last up to seven in power saving mode. An additional battery can added (and charged separately from the computer) without removing the internal battery, doubling your on-the-go productivity to fourteen hours.

The new system will go on sale by the end of March, Sony promised.
