I don’t care about the 90% of App Store revenue that comes in app purchases in games (came out in the trial).<p>I <i>do</i> care about subscription services where at most there should be a one time finders fee and then maybe a slightly higher monthly fee for payments like 5% instead of just enough to cover the processing fees.<p>Also, I just checked out the Kindle app for iOS. There is a link to the book that takes you to the Amazon web site to let you buy the book directly with one (well two clicks) in all. A much better user experience.
