I hate Mac's for some of the same reasons.
Most of the people that have them seem to be either very liberal or see themselves as "standing against the establishment". You are right about the virus crap. Since Mac's are what, 10% of the market, who's gonna write a virus.
They are pains in the ass and suck also. The programs crash just as often, you just don't have the whole computer lock up.
I like PC's. I really hope Win 7 is better. Win vista pigged down my machine something bad. Just to run windows it takes half of my 2G of Ram.
