I don't know. I kind of hate mac, but I'm stuck with one at the moment.
I'd prefer windows just because it's easier to fix if anything breaks. Well atleast I've been told that (technologically impaired).

In any case, I have an imac that seems to overheat ALOT. And I think the graphics card in it is shot. Took it to the mac store and asked if I could get it replaced or anything like that and they said I'd have to replace the WHOLE motherboard or whatever that's called in a mac.
So yes, if I had a normal windows computer, I would simply have to replace the graphics card and NOT the whole motherboard.
A lot easier to fix and besides those silly mac store people are never really helpful...
