But my cybook still won't read these.
Amazon by doing that also prevents people owing a nook / sony / kobo to switi to amazon without loosing this books.
I wouldn't mind buying books from amazon, but hey, wrong format. They win money with kindle users unable to buy books elsewhere, but how many sales lost to non kindle owners ? How many kindle sales lost because the person owns a nook / kobo and can't switch ?
