Wireless Mighty Mouse and it is the worst mouse experience I've ever had.
1. Bad contour: strain on your wrist
2. Crappy scroll ball: no need to explain further
3. Sudden bluetooth connection drops
4. Yesterday I found it didn't register any clicks (right and left)! Reconnecting solved the issue, but having to reconnect every few hours gets REALLY ANNOYING.
I like my MBP, but the MM absolutely sucks. Whatever, I bought it and didn't bother returning it, so the blame's on me.
