Short answer: Nope, still not.
If you have even a passing interest in tech you've seen these types of contraptions before. A laser is used to project a virtual keyboard onto a flat surface, while a camera detects the position of the typist's fingers to register keystrokes.
If it worked as awesome as it sounds, laser keyboards would be a fantastic tool for doing long form writing on a portable device. Particularly when it's integrated into a $180-$190 iPhone case. But the sad reality is that they're almost unusable for any kind of real work.
Not only is the lack of tactile feedback a huge stumbling block for touch typists, but the hardware used to track your finger motions isn't accurate enough for any kind of real speed.
