Compiling data from corporate reports and Bernstein estimates, iSmashphone produced this eye-popping chart showing how much profit the iPhone generates compared to the rest of the industry. A previous estimate was a little more conservative (though still crazy). [iSmashphone]
The article isn't specific, but, at least some of the profit from IPhone has to be in the sale of apps, accessories, etc. With the other companies they sell a phone and that's the end of the profits. I am not pro or con Apple, but that's smart business no matter how you look at it.
