I've been using Linux since 95 or so, I manage about 20 different Linux servers for various services right now. I'm the "Linux guy" among a big bunch of local programmers and sys admins.
But somehow I've never been able to get anything done in gnome, kde or whatever, so my own PC runs XP, but I tend to have just a big bunch of ssh sessions into my servers.
Of course I could do that from Linux itself, but there's something wrong there... maybe the ugly default fonts, the still sometimes flaky vid card support, the cut&paste weirdness among different toolkit applications. I'm just slower using Linux/UNIX GUIs.
Theres a guy here that uses a Sun workstation instead of a PC, and every time I try to get something done there, hilarity ensues...
And on my home PC I mostly play games... so....
