for so long i've wanted to switch to a *nix workstation. but alas, i just haven't been able to do it.
games are one reason, although really i could drop the games for a while and be happy. what's probably the biggest catch is that my productivity apps are all windows (or mac) based. photoshop, macromedia products, that sort of thing. and last i heard it was a real pain to get photoshop to work right with a unix machine. my browser, email and instant messenger client is all unix-native.
unfortunately, i can't really switch to the gimp. it's good, but not photoshop.
i've run unix servers (mostly freebsd), helped admin them, and even ran both red hat and mandrake distros on a workstation a few years ago where i used to work. when i had the seperate rh machine, i did 90%+ of my work on there. unfortunately samba wouldn't run for me, but this was 4 or more years ago.
oh well, either i'll figure it out, or eventually i'll run 2 desktops. although windows has gotten a lot better, xp pro is very good in comparison to what it used to be. and microsoft really can pump out the genius when they want to.
