Yea, well, Ma Bell required me to use winders (on some of my machines). To be fair though, I had a Sun workstation (Sparc 20), and we had HP servers running HPUX, and a nice Sun Enterprise Server; oh, and several NetWare Servers. And I guess I was playing around with a Linux box a little too(1999). And way back in the 80's I had at home an AT&T 6300 Plus (i80286). Came with AT&T SRV UNIX (and curses GUI).
So I'm not a total n00b :)
