I don't get how this helps Apple. They don't want Android copying their API or something? Guess it doesn't matter as long as the iPhone remains super popular. And man, it sucks to spend all that time writing a book, find a happy publisher, and then not be able to release it cause of this.
Seriously? You get some technology, sign an NDA saying you an't publish a book, write a book any ways, and then it sucks that nothing has changed? What exactly sucks other than the business plan of investing time and energy in the hope that someone else changes their mind about an agreement you signed?
