I had Windows Vista, but I got rid of it because it drove me made, because it was a memory eater which really bothered me. I hated it how it takes forever just to open certain programs, files and folders, and copying files was a pain in the a** as well. Well, hopefully SP1 will increase and improve performance. Seriously, if I had to choose to use Windows ME or Vista, I think I'll go for ME. It was less annoying.
