The Steamboxes are here! Well ... sort of. The prototypes for various Steambox designs are certainly here at CES 2013, and we just spent a grip of time acquainting our lenses very closely with them. The devices range in size and form factor, as well as origin -- several of the devices we saw originate from Valve internal, but inclusions like Alienware's X51 and Digital Storm's Bolt were also being held up as examples of the ongoing "Steam in your living room" initiative (note: all the controllers are off-the-shelf Logitech wireless devices, not prototypes). The idea here, as Valve hardware engineer Jeff Keyzer told us, was to show off a variety of form factors for living room-friendly designs. We'll have more from our meeting later today, but for now you can feast your eyes on the elegant prototypes -- as well as Xi3's Piston, and the aforementioned other two third-party PCs -- that we'll be sure to see more of as 2013 goes on.
