Hi Beocool,
I've been using a MagicMouse on my Mac Mini for just over a week now and no ill effects at all.
It's really very nice to use and the ability to use it like the trackpad on my MacBook is great. It's quite heavy and surprisingly firm to grip when using as as mouse to move the cursor around. Definitely the best Mac mouse yet.
Best
Rob
