Actually I think we need a 4th option for your poll.
"I will always stand by my PC, but Apple's extra are worth my time (and $$$)."
I have always been a firm believer in the PC. Sure you have to watch out for a few viruses, but overall that maintenance only requires an hour or less per month. Unless you are a graphic designer or are heavily into video editing, I see absolutely no reason for you to invest in a Mac.
On the other hand now, I will admit that I give in to Apple. I love iPods and have been considering picking up an iPhone for some time now. I know my brother-in-law couldn't live without his. This price drop may end up being the deciding factor.
