I don't see why not, unless Amazon attempts to blatantly sell books in the app, instead of just linking you to the Amazon website like in the iPhone app. And even then, I doubt it. No doubt Apple will make the whole book buying/reading process seamless, and make the interface appealing enough for people to want to buy books from them instead of from Amazon. I don't know many people who use the Kindle app on iPhone as their only Kindle, so to speak, while I do know lots of Kindle owners that use the Kindle app for when they don't have their Kindle around. Lastly, given that Kindle books are mostly text and b&w images (lowest common denominator I suppose), I can't imagine Apple could feel threatened, as the iPad is larger, has a color display, and has a far larger potential for doing more interactive/immersive content, e.g. for education, no matter what Amazon tries to do.
