Hmm interesting, that Microsoft has no 800dpi mouse. Glad I picked Logitech
then. I assumed they were equivalent resolution since most reviews give the
Intellimouse the nod, but I don't know how the heck a 400dpi can compete
with a 800dpi.

Running the Logitech @ 800 on a black surface, it's flawless. I just can't
get it to fail a twitch test, despite having fewer pictures per second. I
did notice it doing a little pixel dance one time on a blue pad, but it's
not ever done that with my black vinyl surface.
