At least I can put my Steam funds to a use then. But, what's gonna bother people is these things are available. For example, Angry Birds is already at several places, and most people would already have it, so Steam or the developers aren't going to get a high profit off of Steam selling it. Yes, there are 4 million people on Steam, probably even more, but I'm willing to bet at least 75% have a game as popular as Angry Birds.
