Yeah, it's pretty bad. The author somehow missed Bezos' comments on Amazon's strategy: make money off of
both the books and the reader independently. Dedicated e-book readers will be around for awhile, even if they are primarily used by the heavy readers (i.e. ones who buy 15+ books a year). It's mostly analysts who drool over reading books on the iPhone who fail to realize there will be a market for dedicated e-book readers for a long time.
However, I do think it's likely that Apple won't sell books through the iTunes store. Selling content for Apple is not a major source of profits; their model is to use the content to lure and tie users to the device. As long as other companies sell books for the iPhone, Apple doesn't have to do it and deal with tons of publishers in the process.
So I guess he may be right... purely by accident.
