I had low expectations on how well this device would react to my “input.” It had no problem displaying a full size QWERTY keyboard wherever I placed it. I was very quickly blown away by how accurate it was. It does feel odd pressing on “keys” that do not move at all. For the first 15 minutes or so I found my self beating my counter top with the ends of my fingers before I finally realized a gentle touch would suffice. I was able to type pretty fast using the laser keyboard with very few issues. It would occasionally be off by one key, but this happened so little as to not bother me. The only real flaw with the keyboard is the obnoxious click it makes to simulate the noise of a mechanical keyboard. While I can appreciate the feedback from the keys in the form of an audible click, it would be nice to be able to turn it down. The loud click made the device embarrassing to use in public.
