I like both, but i'm starting to lean towards mac especially because the requirements vista has, and the price for it is way too high for me and it just doesn't seem all that worth it. If the price goes down I'll go for it. I do like mac because OS X is very nice looking, it's secure and it's very powerful. I also like the fact macs can run OS X and windows on the same machine. PC's can run mac but it's kinda complicated and not everyone has the hardware.
Bottomline: tossup but as of now I'm sorta leaning toward the mac side of things.
