The biggest advantage of Apple's App Store is that it simplify process all around, not just the purchasing process.  Users can pretty much trust everything in the app store without worry about fraud or scammers.  Before App Store, we spend a lot more time research about the app developer and the payment system and worry about if it was a legitimate company or not.  The old ways favor large developers and large companies.  

I remember with Microsoft's "Open" platform, when the software does not work, Microsoft, hardware companies, and application companies all point fingers at each other.  

As an app developer at the time, we often had to support customers who had viruses or hardware problems because the customers don't care who's fault it was, they just wanted the apps to work.
