I'm glad someone posted about this mouse problem. It is the most annoying thing that prevented me from switching to a mac for a long time. I was telling my friends that the mouse was not behaving the same way in Mac Os X and Windows. They were all saying that I was imagining it. I switched to Mac a year ago and got use to it, but I can still feel a difference.
I used a Mac and a PC at work side by side (Often working on the mac when the PC was waking, booting or installing some security upgrades which was a big part of the week, Vista wasn't really any good). But in mousing the difference was clear, Windows had the advantage. I tried switching the mice back and forth but no help.
I also had Ubuntu at home and at my parents' place, and it had the same simple responsive mouse as Vista.
Now I've gone full Mac but it still constantly annoys me at work. If it weren't for the other good things in the OS...
