At work I have my Linux workstation, because I administer Unix servers. It's vital because it has so many (networking) tools built in that are helpfull to an adminisrator.
At home I use Windows XP on a "silent" pc that I built. I do some amature game developemnt and VS.NET 2003 + DirectX is an outstanding development IDE. It dual boots Ubuntu Linux but I hardly ever run Linux at home anymore because after 10 or 15 years of use I still find it kind of exhusting.
I use my Amiga 1200 pretty regularly for hacking around and games. Mostly just hacking around. Also, I occasionally use my Atari ST when I want to play Dungeon Master.
