Amazon announced a new app for the iPhone, allowing its formerly Kindle-only e-books to be read on multiple devices. And Apple is not competing on the e-book front, perhaps because Steve Jobs last year said "people don't read anymore."
Will this further cement Amazon's power over the book business? Will Jeff Bezos be able to dictate terms and prices to publishers, in the way that Steve Jobs has dictated to record labels and movie studios?
Will the book publishers band together and try to create a competitor to Amazon? Just as the movie studios are attempting to learn from the mistakes of the record labels, will book publishers do likewise?
Time will tell.
