Sony's updated VAIO P Series PCs are made for the digital generation who can't be away from their social networks for more than five minutes and don't like to be confined to their desks all day.

"Ideal for busy people who can't sit still, it's the first VAIO designed for simple operation if you're standing or walking. The central trackball is complemented by an additional touchpad and mouse buttons. Duplicating the main controls, they're located at either edge of the screen for comfortable operation with both thumbs while you're holding the computer in two hands," said Sony in a May 10 press release.

The ultraportable notebook weighs just over 600g and measures a tiny 120 x 19.8 x 245 mm. The "ultra-mobile PC" comes with a number of new features not found on its siblings.

The VAIO P (VAIO P11S1E) is the first Sony-made notebook computer to come with built-in GPS and Digital Compass - which comes in handy for keeping track of your location on the included VAIO Location Search software. The brand new location software provides users with a real-time map of their surrounding and comes complete with nearby points of interested and local weather conditions.

There is a built-in accelerometer too, which facilitates shake-to-navigate through photos, PDF pages, or web browsing history commands, and will enable portrait mode viewing for documents or web pages.

Additional specifications include an Intel Atom Z540 processor (1.86 GHz), an 8 inch screen with a resolution of 1600x768, Windows 7 Home Premium OS, 2GB DDR2 SDRAM, 64GB SSD Flash Drive, two USB ports, one SD card slot, one Memory Stick Duo Slot, built-in 3G, Bluetooth 2.1, stereo speakers and microphone, MOTION EYE camera, and battery life of up to 5 hours (10 hours with an extended battery that is sold separately).

For comparison, the Viliv S7 convertible netbook, Sharp's PC-Z1-W ultra-compact NetWalker, and the Archos 7 Home PC are just a few other ultra-compact netbook devices that sit in the market between smartphones and netbooks.
