Query: Unusable

My wrists hurt (I'm a programmer and spend at least 8 hours a day at the computer) so after reading a lot of positive reviews, I gave this keyboard a try. I returned it after 1 week for the following reasons:1. The spacebar is huge and clunky - it makes typing loud, slow and difficult and completely offsets any ergonomic benefits.2. The keys are mushy and feel cheap.3. The keyboard is very ugly and it takes up way too much desk space.The spacebar was the deal breaker for me. If Microsoft had split the spacebar or found a way to make it less clunky and horrible, I probably would have kept the keyboard.
