I get that, but I don't really see how this is going to succeed to the point where everyone is using a steambox, rather than a normal console.
It doesn't necessarily have to cannibalize their own users and directly compete with consoles to succeed, it has a lot of crossover market appeal. The greedy comment is really silly, all products are designed to make money. It's how they go about doing it that matters and that remains to be seen in this case. Valve has a pretty good history of consumer value and customer friendly decisions so I'm not worried.
