Macs are better for video editting (less stutter) and that's about it. As a big computer gamer I also shun Macs since so few games get ported over. The upgrade issue is also a big issue for me, I don't like the idea of not being able to upgrade things myself as I go along. And this may just be my geekiness talking, but I like to have a computer I can get elbows deep in tweaking things
