So far handiest gadget of the short year of 2009.

It gives you a portable laptop-style touchpad in the palm of your hand with full media controls and a built in laser pointer. The built-in rechargeable battery gives you 4 hours of play time and you can charge up via USB or docking in a standard PCMCIA slot.
