@Translation and mini rant
I have three computers. One is a dual boot machine with XP and Ubuntu. Another is an Asus eee PC with the original linux OS. The most recent is a 20inch iMac.
I've never used Wine or virtualisation. I suspect if I did I wouldn't need the XP partition anymore. In fact I am not even sure why I do need it. Occassionally I use it to test what my websites look like in IE. But overall I find it slow and unresponsive.
In my experience XP takes a hell of a lot more configuration to get it 'working' (if you can call constantly having to manually update spybot, adware and clamwin anti-virus just to keep it secure 'working'). With Linux everything has just worked out of the box, and when I'm at home I am pretty much always in Ubuntu.
I use the Mac almost exclusively for editting film using Final Cut Studio 2. Although its also portable enough to be moved into my bedroom for the purpose of watching DVDs in bed. Overall though I get frustrated by the single button mouse and the lack of right click context menus. I still find myself trying to right click sometimes, and then wondering what I'm supposed to do instead.
Overall I like Linux. And I know plenty of people using Ubuntu now whose degrees are in the Arts. I've never had to configure anything for them. Things just work out of the box. At least they do for me. Not with XP though. And the only copy of Vista I've seen was running at a crawl. Maybe there is a way to configure it, but non-technical people don't want to be bothered with that. They'd rather an OS that just worked. Like Ubuntu.
