"Apple's app policies" pretty much state if you play in our ecosystem, you do so entirely to keep it holistic. Of course they are a business and these policies ensure that their "walled garden" is maintained, much in the same way Amazon's ebook DRM does for them. RDIO did the smart thing and adopted in-app purchasing w/ a surcharge if you do it in-app. The intention seems to be "pay for the convenience" as well as making sure their ARPU is intact regardless of method. That being said: has anyone calculated what the per-transaction overhead would be if a developer wanted to institute in-app purchasing themselves? Considering Apple handles CC processing, chargebacks, customer service on the purchase, verification, etc?
