I haven't bought a Steam game either. In fact, I don't even have an account. For the past couple of years I've been locked into the MS ecosystem with the Xbox 360. I will not buy the Xbox One though. I don't need a surveillance machine in my living room. I was never a fan of the PlayStation. For a while it looked like I had to build a PC and have it run the system I dislike the most, just for the sake of gaming.

Seriously, I'd buy (or build) a SteamMachine in a heartbeat. It's the most sensible option for me at this time.
