I've been monitoring some of the Vista newsgroups and you'd be suprised at the number of trolls who post over there saying something, like "Vista is for losers, Linux rocks!" (actually, usually "Linux rocks, dude!"). There's nothing wrong with choosing an OS simply because it's Not Microsoft, but Linux on the desktop is clearly not fungible with Vista (though I could see someone who needs only basic word processing, mail, web browsing and the like managing with a Linux box).
