I'll admit it: I'm an apple fanboy. I'll buy just about anything, regardless of price, if it's made by apple. But I'm having a hard time getting myself to buy a "Magic Mouse". I have the Mighty Mouse with the trackball, and I got crumbs and random food particles stuck in the trackball, so now it doesn't scroll. I need a new mouse, BADLY. But I won't go out and buy a $10 HP mouse because... well, I'm an apple fanboy. But I tried the Magic Mouse at a local store, and can't get into it. The lack of the side buttons for activating exposé is my main concern.
So, is the magic mouse worth it, or should I stick with the Mighty Mouse?
Noooo... Apple is a big fail on mice. They just don't know how to make a usable mouse. Do not buy! The thing is in an unusable form factor, the scroll wheel is unusable and at least from my impressions in the Mac store the actual moving of the mouse/pointer is lame.
Stay away and get a mouse from Logitech or Microsoft.
