Intel has unveiled a prototype of ultraportable with a trackpad as transparent as glass. The device is called Nikiski and runs Windows 7. Although transparent, the trackpad is quite functional. The computer is able to differentiate between a person who relies on his wrists and use the trackpad with his fingers. So we will not make false manipulations.
The real interest of this translucent portion is more evident when the ultrabook is closed but running. It displays the interface used by Metro Windows phone 7. This interface lets you control the computer even being closed and can also monitor the arrival of new messages for example.
The Nikiski ultrabook currently in the prototype was unveiled at CES 2012 and will be available only in a few months.
