I just spent a little under $2000 getting myself set up with a mac, and I have one little issue thats making using it a nightmare. The mouse (a logitech dual optical) feels AWFUL. Its an acceleration setting I think, low tracking speed (even with it set to max in preferences) and high acceleration. It works flawlessly in both linux and windows. Google has found a few people with similiar issues, but a lot less than I'd expect, and no solutions. It seems strange that an OS that has been so highly praised as configurable and intuitive has such a horrible default setting, and no apparent way to change it ? In order to make this mac useable, I need to disable mouse acceleration. Does anyone know a way to do this? I've spent about 2 hours in OSX so far, and I'm already starting to loathe it due to my constant battle with the mouse. I realise this has been a very negative post, but I'm not trolling. Just very, very dissapointed.
