A laser projector is probably going to be quite energy efficient, a la laser pen. what would be cool is a small PC with one of these in one end, and a IR laser keyboard in the other. plonk it down on a flat surface near a wall, up pops your desktop, and a keyboard appears on your desk. When youv'e finished working, pick it up, and stick it in your pocket. Makes more sense to me than a UMPC.
