Yea I agree about the Microsoft part, but who needs 3200 dpi? 2000 is too much! I use 1000 and it's really all I need.

Well yeah, I dont know, I never played with more than 2000 dpi, but as Im using 2000 right now (and it seems not to be enough, I still have to move my whole hand sometimes as opposed to wrist only what I would prefer) I'd kinda like to be able to go higher if it in fact increases my personal performance. The sky is the limit!
