Yeah...ok. Windows is for people who don't mind dealing with viruses and crap like that. I'd say that the majority of people wouldn't need to do anything on a PC that they couldn't do on a Mac.
I got Parallels when I first got this MacBook. I used it for a few months, but I got tired of dealing with it so I just replaced the one or two programs I was running on parallels. No more windows.
I'm forced to use a laptop PC for work...but it just reinforces my belief that my mac works better. My 14 month old issue Dell died (system failure) a month ago. My 5+ year old MacBook Pro continues to work perfectly. Like I said, you're welcome to your PC's. IMHO.
