here's the one downside: will internet providers begin to throttle bandwidth because of stuff like this and NetFlix completely hogging all their resources? That's the wildcard in this equation and if the answer to that question is yes, then expect yet another failure.
That's not a wildcard, that's already reality. AT&T has a 150GB/month bandwidth cap. It's 250GB for Uverse but that's not available for me.
I'm not sure this is competition for Nintendo and Microsoft so much as it's a consolified PC gaming. If I were looking for a (I'm assuming) low-endish PC that could handle games and didn't want to have to worry about buying new video cards and more RAM all the time I can see this being a good option. Plus the Valve/Steam name brings a certain level of trustworthiness with it, no?
