I'm just going to throw in my 2 cents here. Both systems are good for their own thing. Mac OS X is the first operating system that I like out of Macs. It's good for video editing, website design and other things on that area. Windows, altho they can do that to, is not as good at it, to where it's harder to use their editing programs. Windows is more for the people who like to build their own pc's and are for people who game on pc's. Now I realize that some games are also for Mac (like WoW) but pc's are better in that department. Both can also have their own problems. For Mac, it doesn't have a lot of virus', but the reason they don't is because not a lot of people use Mac's, the majority of computer users use windows, which is why no matter what, you should get a virus protector and firewall anyway.
