Running Windows 7 dual-booted with Mint 9 Isadora (LTS)...I used to have Windows Vista as well (triple-booted) but I got rid of it because Halo 2 sucked after I finished the game (Halo 2 has a low replay value in my opinion).
I mainly use Mint 9 (90% of the time) because as a college student, distractions like games don't help, and with Windows, that definitely is an issue
Mint helps me get work done faster, plus, it's also my entertainment--whenever I get bored, I usually look up terminal commands, cool Linux programs, or post on the forums (for example, right now
). So yeah, Windows for games, and Linux for work related stuff + curiosity + "just for fun." I use Gnome most of the time, with Compiz and 3D effects on full blast, but, my graphics card busted so currently I'm using LXDE (and it STILL looks EPIC!) with xcompmgr and transparency stuff on. Most likely getting my gfx card back from EVGA next week (I have a 2 year warranty on my GT 430, so all is well!). I also use Fluxbox sometimes, but I think it looks crappy (no offense, but we all have different opinions, right?). I prefer Openbox to Fluxbox.
