What are some good Mac mice? That has 2 buttons or more, by the way. I'm thinking of the MX1000? Also, I like my mouse to be as sensitive as possible. I've set my sensitivity to max, but it still moves slower than on my Windows. And when I really want to move slowly on Mac, it moves super-slow. I'm thinking of going full out accurate, and getting a MX1000 for Windows/Mac.
