@Shirotsume ... what are you talking about? I've installed steam on ubuntu before and, while it isn't as easy as windows - it's not the nightmare that it was before.
Having said that, after a re-install, I find myself just rebooting into windows just for steam. Sure, I can run it in ubuntu, but I'm too used to windows and it's odd quirks to deal with steam on ubuntu. Hmm.. actually, I don't I ever had a real problem with steam on ubuntu. It was just annoying to see it pop-up on start-up and I was just too lazy to dig in to switch it off.
