Yeah, I have another comment from a different thread saying the same thing I'm about to, but the amount of linux compatible steam games has really exploded since the original Steam OS announcements. I think it's almost at half the top 100 most played games in Steam, but last I checked more than half of my steam library was playable on ubuntu at least.

I wish it worked on Debian, it used to but the last time I tried I lost a day and still didn't get it to run...
