Apple’s upcoming iPhone software development kit will do more than enable programmers to create new software for the iPhone and iPod Touch.
It will also turn iTunes into a software store, because Apple will probably use iTunes as the primary distribution vehicle for what’s likely to be a massive community of iPhone software developers. In so doing, it could usher in a new way of buying low-cost software that’s both easier and faster than downloading shareware or purchasing shrink-wrapped boxes.
