Sony is billing their X-Series as the "world's lightest notebook". At just 1.6 lbs, his new Vaio definitely qualifies as petite. All Sony has told us about this new notebook is that it is tiny, and that it packs an 11.1" screen. Thanks to leaks from Boy Genius, we may now know a little more of the story.

Apparently the X-Series will come with normal, and "super-extended" battery options. The normal battery will be good for 3.5 hours of life, while the extended battery is said to last up to 14 hours. The X-Series touchpad is said to feature multitouch functionality, which is also something worth getting excited about.

We don't know what processor this new carbon fiber Vaio will pack, but we do know that it will ship with an SSD of some size. The launch OS will be (what else?) Windows 7, and the price at launch is set at $1,499. Ouch.
