iPhone mobile applications

The iPhone rollout is interesting to me. In the end, do they expect users to own both an ipod and an iPhone? That kind of expense will surely limit the number of adopters to the general public. But if that isn't the case, they will be cannibalizing sales of the iPod as the iPhone gets larger and larger storage space.

In the end, I don't know how it will shape up, but there will soon (if not already) be a huge glut of iPhone apps if it doesn't go mainstream like the iPod.
