>>you can avoid the 30% if you want by having a free app with in-app purchases that you process via some other mechanism.
No, the Apple developer agreement doesn't permit external payment mechanisms (though it is true that that some apps have been able to use external payment mechanisms because of app-store-review inconsistencies or because they obtained prior approval from Apple)
[edit to respond to rcoder]>>Actually, you can round-trip users through Mobile Safari and process payments however you like
No, see what I said above. If you turn on functionality based on external payment mechanisms, your app could be rejected.
Actually, you can round-trip users through Mobile Safari and process payments however you like. (For example, Amazon does exactly this for the Kindle app.) Users simply can't click a "buy" button in your app and have it pass through a processing system other than Apple's.
