I have heard of virtual keyboards, but I had never seen one in action before. This virtual keyboard is the i-Tech Virtual Bluetooth Wireless Laser Keyboard for PDA/Smartphone. It uses light to create an image of a keyboard on any flat surface. The unit is quite small (about the size of a matchbook), much smaller than the picture makes it seem. To me, it also looked much stranger in person than the picture indicates.

The person I saw using it seemed to be typing at a decent speed. I think it must be an acquired taste because I like travel on my keys. Still, the i-Tech must be the most compact portable keyboard possible.
