What do gamers think of Valve’s new Steam Controller?

It’s been a couple of weeks since Valve sent out prototype Steam Machines and Steam Controllers to beta testers. At the same time they released SteamOS to anyone who cared to download and install it. The community is starting to share their thoughts on Valve’s grand experiment. I haven’t seen a lot of discussion about the Steam Machine itself, and most SteamOS talk seems to be coming from Linux fans. I’m guessing the lack of feedback is due to the OS being so early and the fact that there’s just not a lot of content available for it yet. That’s understandable of course, and in fact Valve seems to be, if anything, trying to dissuade average gamers from bothering with SteamOS this early.
