I just returned from my genius bar appointment for a one key problem. The h key is wonky. It feels different than any other key - you either have to hit it on the very bottom, or bang it really hard. It will work, as all the "h'' in the post show, but it's hell touch typing with any speed. I had to convince the genius it was a problem as the keyboard and controller passed the diagnostic tests. He could easily tell the difference when he hit the key himself (too many h's in this post). I finally said, "Look, I'm a touch typist and this is hell to deal with." So he said ok and ordered me a new keyboard. Now only two more trips to the Apple store next week. Any one else have trouble wit just one key?
