1. Backtrack Linux.
2. Fedora Linux. I'd use it, but my video card drivers don't work (screw you too, ATI) and I can't play WoW through Wine.
3. Mac OS X. It's pretty nifty, and I end up using it most of the time.
4. Ubuntu Linux. It's Backtrack, without the hacking tools. It's alright, I guess.
5. Slackware Linux. It's a pretty nice distro, but I had issues with wireless, so I left.
6. Gentoo. I don't like it. But, I don't really use too many OS's. So, this makes the list de facto.
7. Windows Vista. I hate all forms of Windows, but I have to fill out this list somehow.
