Vista doesn't come with every new PC, you can still get XP on it if you'd like.
Anyways, about the article. It was a nice read, and regardless of what's a fact and what isn't, I'm glad there's some people that want Microsoft to lay down and just die. You want facts? Find someone who's never used a PC before. Install them Windows and install Linux, or maybe show them a MAC, and see which one they think is easier to use and in general "better". Guaranteed they won't choose Windows. :)
