>>>iBooks suffers the same price disadvantage relative to Amazon
I like Apple's iBooks for altruistic purposes. Before Apple got into the game, Amazon was taking 70% and giving authors 30% of the sale. Apple turned that on it's head. Even today, they impose their 30% or 35% author payout on many occasions, such as sales to certain foreign countries, or if your book is priced at a certain amount. So, I think Apple is more fair to authors.
