i got my new c2d mbp last friday and installed boot camp on it. i plugged my old microsoft intelli-mouse in and while it works under both os's, it feels noticeably jumpier (hence more uncomfortable to use) under osx than when i boot into winxp. anyone else experiencing this difference? do i need to get a new mouse??

just played around with it some more, so i'll try to be a little more specific. moving the mouse around at a higher speed in osx is fine, it's when i'm trying to move it more slowly, like trying to select an icon that i feel the mouse is harder to control with more precision than under winxp. i don't know if it's a setting problem, something with the mouse, or just a difference b/w the 2 os's. any help or suggestions would be appreciated.

The difference is in the settings in the two different OSs. Have you played with the mouse tracking speed preferences in OS X? I think mouse acceleration is automatic, so the basic tracking speed setting should be all you need to mess with.
