Apple's new rules mean that apps can offer access to content purchased outside of Apple’s walls, as long as the app doesn’t have a “buy†button that connects consumers directly to an external store. If there were a (micro)payment service with a great user experience and much lower fees than Apple's 30%, would iPad developers want to sell iPad content through other channels besides Apple: e.g. their Web sites, third-party stores, etc.? How would you most likely sell that content?
