Laser Typing VS physical keyboard, which one will you choose?

Projected keyboards are all the rage! This one, by Celluon, doubles as a virtual multi-touch mouse, eliminating the need for extra peripherals. With the flick of a switch, a full-size QWERTY keyboard is projected in the safe form of a laser directly onto any flat surface. Compatible with both Windows, Android, Blackberry and iOS systems, Epic pairs via Bluetooth to your favorite devices.
