Apple Thoughts: iPhone 3.0: In-App Purchasing

Answering the requests of developers, Apple has implented in-app purchasing for additional content. An excellent use of this would be in an app like Kindle where you could buy a new book from inside the Kindle app itself. Other examples include purchasing in-game content like weapons or costumes (like in the SIMS) or even clubs in Tiger Woods (a feature already in the XBox 360 version that I hope makes it into the iPhone version).

Developers will definitely like this new revenue stream, and users will appreciate the extension of their application purchase by adding more to it. This is a small thing, but can work out to be a great thing for everyone involved.
