What are the Operating Systems (OS's) have you used so far?

Question

Personally, I've already used all of the versions of MS Windows (From the oldest Windows 3.1 to the newest Windows Vista). Coz I'm a PC guy. :)

Sometimes, I do use Mac OS - from somebody's Mac computer. But that was long time ago.

All my life, I never used UNIX or Linux until now. :(

Anyway, to find out some simulations (It is almost like you're using the OS's), here are some of the sites I want to share:

Answer 1

I would say all of them but there are over 300. Altho I have used most that anyone knows. Hmmmm lets see.....
Unix (3 versions)
Commodore (yes it was an operating system)
DOS (when it was the operating system)
CP/m
Atari
Windows (all of them)
Mac (2 vresions)
Linux (4 different versions)

At the moment, I prefer WIndows XP for my desktop machines, Linux Debian for the servers I run from the house, Unix at work, and Mac for portables
