Just wanted to let any of you considering buying one that the Magic Mouse rocks! I have one of the Mighty Meeses from a while back and had the legendary problem of gunk keeping the scrolling from working. Well, there's no place for gunk to go on this thing. It's made of a lot more metal on the bottom, and the top surface feels a lot like the new MBP trackpad. The buttons are the same as the Mighty Mouse, but the scrolling works anywhere on the mouse surface. My dad got a new iMac and didn't really care to use it. Win for me. I will warn you to test one if you don't think you'll like a very thin mouse. This is maybe as thick as a deck of cards. It's probably more like half a deck.
