Sony has launched an 8-inch netbook, saying it expensive. The company claims is the lightest in the market at 1.4 pounds.

The netbook is said to be size of a business envelope and as thin as a cell phone. As a result, the device is small enough to slip into a jacket pocket or handbag, while still delivering full PC functionality.
Sony plans to offer its product through its stores this month for about $900.
Other nebooks cost as little as $300. The system runs Windows Vista, but has an instant-on option that launches directly into Sony’s Xross Media Bar interface, which provides access to music, video, photos, and the Web.
The netbook will be available at other major retailers in the United States in February.
In releasing the Vaio P Series, Sony apparently believes there’s an underserved high end of the netbook market.
