I think that the "Mine's Better" Ideology of people who have only tried one OS is laughable. I mean, don't say yours is better unless you have thoroughly and unbiasedly investigated the others. I like my vista, but I bet I would like Linux or Mac too. I'm just not at the point where I might switch. According to the reviews and independent comparisons I have read, Linux is a favorite for coders and computer savvy people, Mac is for people who are novices and are not as good with computers, and Windows has the huge market share. Of course, beginners could use Linux, Mac users might be pro coders, and windows people might not necessarily like their windows. (Example: I hate some features of my windows, and 70% of Microsoft employees confess to use Google, not MSN.) Although some of you have tried all 3 big OS's, so you can be a good judge.
