But speaking of mouse rates, I downloaded those progs. My MS Intellimouse 3.0 optical gets around 125 in mouserate. The touchpad gets around 75. I tried resetting the rate to 200 with ps2rate, but it doesn't seem to "take" or make a difference. Anyway, I'm fairly satisfied with the performance. I use the mouse 99.99999% of the time. Pack it for travel, use it on the sofa surface if necessary. Does alright, though there's better out there I hear.
