having used computers since the commodore 64 days, I'm not ignorant enough to think that either one (apple or pc) offers up unlimited computing with no problems/issues. i do think the apple os is more stable than vista and less likely to draw the attention of virus/hax0r retards, but that's not to say it won't give me problems from time to time.
apple-
i get to learn something new, love the "all in one design" of the imac with a huge 24 inch screen, known for more graphic art related crap
pc-
cheaper than apple, can build myself, wires everywhere and cluttered, big, can buy a big monitor from dell, already know how to use, vista sux
