Ya think at some point Valve is gonna regret handing out their branding to a bunch of (apparently) morons?
Right now, if I blank out my actual knowledge to become the "entry consumer", a Steam Machine is a (possibly) slightly more game optimized system, but probably costs more, uses this wacky new interface I'm completely unfamiliar with, and has a drastically reduced library of games because of that. Unless I'm staunchly trying to avoid Microsoft (not really something an entry user is likely to have a firm opinion on), what on earth is the incentive to buy one of these things?
Its hard to tell if Valve has misstepped here (it does seem they've failed to regulate what their branding is at all), or they actually just got incredibly borked by all these hardware guys going "Eh, well just slap the OS and name on one of our random configs and have at it".
