I have a logitech USB optical mouse. It works fine on my powerbook, my only issue is that the damn thing takes two strides on the mouse pad to make from one side to the other! I suppose with such a large amount acreage a bigger mousepad could be in order... but I've considered loading the Logtech drivers onto my machine. I've already made the mouse as sensitive as it cna get on the OSX preferences, but still, i want my mouse to fly across the screen... does it make sense to get the logitech software/drivers? 25mb installer...
maybe this should be put into the peripherals forum? if so, my bad.
