I don't have a problem with paying a business partner 30% if it makes sense. In the past, I built a business where I only had one client, IBM...they sold my app frameworks into their clients...big honkin' enterprise deals. They dictated the terms at all times. Life was good for a few years, but the party did end. My issue with Apple isn't how much they want for their cut, its that there is no choice...only one market, they control all the terms.
