I just received a Magic Mouse from eBay and although I LOVE the ability to be able to perform OSX trackpad gestures on it, the actual mouse functionality is so poor. It's sensitivity is very bad, frequently lags and sometimes doesn't seem to receive the movement information properly.
Is there another mouse that can perform OSX trackpad gestures? I was thinking the Microsoft touch mouse? It would be great to not have to buy a Magic Trackpad...
