That I am a Linux user. I would probably be just as happy as a BSD user or an OpenSolaris user -- and I'm really glad that I'm not really a Windows Vista user. I used to keep a Vista partition around to test Corel Painter X with (because Corel Painter doesn't install under Wine), but seldom boot Vista.
So, when I last booted into Vista, it had an enormous backlog of updates to install. Which I foolishly allowed it to do. The result? Something called winload.exe is apparently borked beyond recovery. A quick google shows that it's apparently a know problem. Right... Breaking your basic OS kernel loading during an update, that makes Ubuntu's X11 foul-up look good in comparison!
