> Will it run games not distributed through Steam?
Given that SteamOS is supposedly an open, Linux-based platform, I don't see why it wouldn't? It's pretty much just a standard Linux system that boots into a full-screen entertainment interface (an extension of Big Picture mode) by default.
Switch into the desktop interface (there'll be a key combo), download and install whatever you want, and add it into Steam as a non-Steam game so you can launch it from Big Picture mode.
Also, you could install another OS on it and dual-boot quite easily if you wanted. It's a PC.
