>Also, Apple will claim they have a better product that warrants higher margins. And this argument is fine in the hardware market because they have competition, it's efficiency monopoly - that's why I said it's not always bad. However their app store controlls access to 50% of US market (even more by revenue) simply because it comes as the only option and the consumers can't unbundle it. If they had competition on the platform (different stores/distribution methods) - you wouldn't have to say what % is right, the market would decide the value added by their app store/payment methods.
