Economics in the Apple Store

Fascinating piece in Fortune about the economic realities of Apple's IPhone application store. Very good statistics. As we know, 'free' is a very different marketing reality than just a small cost. You can see this by reading the review comments for each of the free items for the lowest price applications at $0.99. Of course even free apps can have a marketing value, a trade up value, even a personal status and branding value.
