I wish I could love Magic Mouse, but it is way too small for my hands. Steve was tall and it is likely he had large hands, but the product had to appeal for the masses. Mouse can't be all for one.

Mighty mouse scroll wheel was amazing and I still lust for it, but today I just use magic trackpad - it's flexibility with gestures and low profile helps with fatigue. However I find repetetive and quick tasks to be done easier with a traditional, ugly and cheap wired mouse.
