I found my Mighty Mouse poor, but dunno. Was an original USB one, and the scroll wheel packed in.. and it was over sensitive.
Logitech MX1000 is by far THE best mouse in the world
I don't use it on my Mac tho - only use Trackpad on it.. I guess if I ever get an Apple Display etc.. and use this MBP as a proper desktop, I'd use an Apple keyboard and my MX1000
