I just bought myself one of these and my wrist is thanking my already. I've been looking around at alternative input devices for a while now, and had been considering a tablet and stylus in order to get my hand in a more upright position. Today I got fed up with the pain in my wrist and went out on a mission to get something. This seemed like an excellent solution to the problem. I've got 15 days to try it out, but really, after a very short trial I'm already sure that is, literally, just what the doctor ordered.
