It took a few hours of messing around until I finally decided to follow the Asus-Linux tutorial, which worked flawlessly. My suggestion for anyone looking to make the jump, follow a tutorial. (I thought my tech skills would be enough, but there are some gotchas)
Anyway I installed Steam last night! (And ran into an issue playing Dwarf Fortress, classic Linux... but at least I don't have to worry about M$ hijacking my filesystem anymore!)
