I think that the Magic Mouse gave me a mean case of carpal tunnel syndrome. I have been having shooting pains up my arm and an inability to move my fingers for a few weeks now. I finally decided to switch to the 3M ergonomic mouse. Yes, it looks completely dorky and it is awkward to use right now. I’m going to try it out for a few weeks – if I can stand it – and hope that it will prevent my hand from falling off.
