I don't understand why everyone here appears to be "on the side of" the carriers, google, apple, etc. The app developers give a smartphone a sizeable part of its value (half? more?), and they're getting screwed because the other players hold a strong position. That the carriers and makers invest a lot only means they get the chance to screw the weaker players, not that they deserve the bigger part of the pie, that argument is absurd. Does nobody see this? I commented on this situation before in this other thread too: http://news.ycombinator.com/item?id=3635861 http://news.ycombinator.com/item?id=3635861
