Has Apple changed the world again with the release of the iPad? To app developers, the change is both subtle and enormous. It’s subtle because the new OS version 3.2 is only a minor update from the previous version 3.1.2, and because there are few changes in the APIs(just some additions). On the other hand, this is an enormous change because the iPad presents an entirely new market for both existing and new applications. It is likely to spark another “app gold rush” similar to what we saw when the App Store opened and the iPhone SDK was first released two years ago. It also significantly changes the development paradigm for programmers of iPhone apps.
