From the way-way-way-too-cool department: the virtual laser keyboard. You press a switch and it laser-projects the image of a keyboard onto any surface, then detects your “key”-presses on it via bluetooth. No stuck keys, no getting food jammed in it, or coffee poured over it. At US$199, it’s not particularly cheap, but for pure cool points, it looks like a winner. There’s a gushing review here.
