at home: Windows XP on my main, linux debian (well ubuntu, its still a debian distro) on my laptop but thats dual boot with xp too, at work 3 computers, 1 windows xp 1 debian linux and a mac using VNC to join them all together, i hate mac so i dont use it much unless i need it to see what bugs IE on mac has for me to fix. Tried vista once and got instantly annoyed with it and disposed of it
I use vim to edit usually on linux.
