Gruber recently said that contracts with publishers are generally set up in a way so that they get about 70% from all revenue. This would obviously make it impossible for Amazon to sell books on the iPad. (The publisher taking 70% and Apple taking 30% leaves them with nothing at all. Increasing prices, even if it were possible, wouldn’t help.) That's obviously not a workable situation, if Apple doesn’t change anything Amazon will just stop selling books on the iPad. (Gruber speculates that Apple will drop its cut for at least some in-app purchases down to about 5%.)
