Steam Machines are just custom mini-PCs build for the living room, they will be compatible with all Steam games. So they ALREADY have lots of killer apps....
Brilliant move Valve! You waited quietly for the others to announce their "next-gen consoles" and then you came out suddenly with these marvelous announcements full of promises and innovations, taking everybody by surprise and not giving a chance for the "others" to react, as their "next-gen" consoles are just a couple of months of release, they can't do nothing about your potential threats now. I applaud you, Valve.
