One thing that web apps lag behind now is the "micropayments" thing. The eponymous "in-app purchase" is a damn sight easier for the end-user to understand and use ("Do you wish to purchase 99 potions for US$0.99?" Yes/No button). Because the App Store already has your card on file, they can do this with minimal friction. Same goes for Amazon.
