Guys, I need help with this. I'll be buying a new iMac this year, 27''.

..and I'm thinking if the Apple's Magic Mouse for games such as upcoming Diablo 3 will be the right choice.

I'm using an old Mighty Mouse, and I'm sure it would be a great improvement.

So.. how good is Magic Mouse as for gaming? Anyone tried playing SC2 or any other mouse intesive games?
