LIES!!!
... I'm afraid I'm also in that minority. I've had three computers with XP on them and I've rarely had any problems. And the ones I've had are usually related to entropy or a hardware malfunction rather than Windows.
(Though my mom and dad went through hell using ME.)
But I'm still switching to Mac because of Vista, the awesomeness, and there are a lot of very satisfied reviews.
And the iMac makes me horny.
Nuff said.
