> If customers choose to buy ebooks for a significant mark-up because they like the way Apple delivers them, I don't see how the price fixing harms the market From some reading, I think the issue is basically that as a result of Apple's collusion with the publishers, Amazon could no longer sell without significant markup - thus price-fixing. I could be wrong.
