Part of the problem here is that when you read these interviews with Steam, it is clear they don't even know what SteamBox is going to be themselves. Any company that even attempts to break into this market needs real management with real ideas and not someone that thinks they have a vague idea of what they might possibly one day want to start thinking about developing. You need real R&D with real management, real market research and real capital.
This reminds me a bit of OnLive. The same sort of buzz was around it and I knew at the time it was going to be a big flop. Yes not quite the same thing but just someone else that thought it was easy to take on the Big Boys. How's that working out...? Check this out.
