A look at the most exciting gadgets of CES 2009

Netbooks were originally introduced as consumer devices but, thanks to their cost and portability, have always had potential for the business user.

HP's latest, the Mini 2140, is explicitly billed as a business netbook. Launched at CES on Monday, the machine has a brushed aluminium chassis and includes corporate-style features such as 802.11n Wi-Fi and HP's DriveGuard technology. DriveGuard uses an accelerometer to warn the hard drive if the netbook has been dropped, quickly parking the disk before the PC hits the ground.
