Meanwhile, if you're like me and don't like how the mouse or trackpad respond, you're SOL, because there is zero configuration allowed. Try using a non-magic mouse on a mac. It's hell.
I paid $20 for USB Overdrive, an excellent third-party driver, so I could continue using my ancient MS Intellimouse when its drivers took a turn for the worse. You can set speed and acceleration separately, and the curves are as good as the MS ones.
