Joe Cieplinski, developer for Teleprompt+, has the same reaction to Marco’s post as I did:

The fact is, there is a whole world of untapped potential on the App Store for developers who can solve real problems for people who are happy to pay. I’ve said it a million times, but it bears repeating: it’s not about price; it’s about trust. People are willing to spend money if they are sure what they are getting will solve their problem.

There are so many potential business models in mobile development that declaring any one of them “over” is just silly.
