I use my Linux box for bittorrent, video editing, audio editing, gaming (ID Software and Epic release cool games for Linux. Doom series, Quake series, Wolfenstein series, all the Unreal Tournament series games. They all work great!) 3D modeling (K-3D) and surfing the web, listening to music and all the sorts. It has yet to hickup and give me a major problem that I couldn't fix (except that damned Xorg.conf

)
I have to use Windows at work everyday for AutoCAD, and I must say that Windows gives me all sorts of problems all day long. Then I go home to my Macbook Pro and my Linux box and have no problems at all.
It really must show something about Windows.
I wouldn't really say I am biased, as I have to use Windows all day long at work Monday-Friday, but I would say that I am going to try hard not to have to ever use Windows Vista regularly. I installed the public beta and it is less-than-impressive.
