The highly anticipated VAIO X Series is the world’s lightest notebook at just 655g, and measures 13.9mm thin, has a 11.1” X-black widescreen LCD and up to 16 hours of battery life.

It will also cost an arm and a leg at $1,499 (£933) and will ship with an SSD drive and Windows 7 Home Premium.

No word on what CPU it uses yet but at that price it better had be one of Intel's new ULV CPUs.

Below is an interesting image from Sony showing the innards of the X Series.
