I had the kindle app for about a year before iBooks came out. I bought some books, but having had an unfortunate incident with Amazon taking a book I'd bought away from me in the past, I didn't invest much time in it.<p>The Kindle app is so clunky it might as well be a webpage.<p>Once iBooks came out, the experience was so much better that I was happy to switch. I now have several hundred books in iBooks, including all of my technical books, lots of free books, pdfs, DRM free ebooks from people like pragmatic programmers.<p>If amazon were to release books in a DRM free epub format, I'd buy them and read them in iBooks too.<p>But for all the gnashing of teeth and exclamations from people who seem to think this is the Great Tragedy of The Ages, I'm amazed that after so long people haven't figured out Apple's priorities.<p>Apple does right by the customer. It is the key to their success. non-discriminatory pricing is right by the customer. consistent-terms across sales methods is right by the customer, and by the developer.<p>Imagine if subscriptions were only %10 while sales were %30-- suddenly instead of buying your apps we'd go back to the way things were before liberated the mobile landscape, where if you wanted Doom on your phone, you had to pay $2.99 a month to rent it.
