The Magic Mouse has been a delight to work with. Overall it’s comfortable, tactile and all around nice to use. Happily I’ve made it my new daily desktop mouse. The Expose functionality the Darrell mentions is not an issue I’ve ever bumped into, however I use the whole pointer in the screen corners when I need these things so the workaround there is pretty dead simple.

There are 2 things I’ve found to be potential issues:
1- If your hand sweats at all, you’ll find scrolling tough as your fingers sort of squeak across the surface. It’s not a common thing for me so not a deal breaker.

2- In the commercials, if you flick on the scroll, it scrolls faster and then slows down. Mine doesn’t do that for some reason. Again, not a deal breaker.
