Edit: After further research, I found that this fix only adjusts the speed at which your mouse moves. It doesn’t do anything for the acceleration curve. I recently picked up a Magic Mouse and discovered that I like almost all of its features. The biggest headache is the funky mouse acceleration curve that it applies by default. When you make small movements, they barely even register on the screen. When you make big movements and slow down a little mid-move, the pointer slows down much too rapidly.
