At college (university for those who prefer that word) we used Sun boxes, Vax, Dec Ultrix, and a few Indys. They were neat. But I'd probably be using an x86 Linux box dualbooting Windows and Linux, couldn't say which would be default, or perhaps a Mac with OSX. More likely the x86 though, as I've got 3 of those with my Amigas, one with WindowsXP and two with Linux, none currently dualbooting though. I'd like to get Amithlon dual-booting on my Windos box but haven't got around to that project yet.
