I couldn't care less about the Steam Machine hardware. You can build that yourself and just run SteamOS on it if you want something for your living room.
I am more interested in the Steam Frame. Something I can't build myself.
Yep, when it comes to something truly more progressive, the Steam Frame is definitely more exciting. Wireless VR with some good specs to boot is pretty cool.
Edit: I honestly keep forgetting about it which is sad since there's a pretty good chance I'll end up getting one.
