Not really. But if you decide to buy one, please don't pick the Magic Mouse... it's expensive and it sucks.
You'll be better off with an average USB/bluetooth mouse.
Any suggestions on a bluetooth mouse?

Hey, speak for yourself.
I use a magic mouse 8+ hours every day and I love it - especially with an add-on app like MagicPrefs, which lets you define custom gestures.
Another thing is that I believe you lose the ability to smooth scroll if you plug in an external mouse. That's a deal killer for me
