> once you've got that original library of books on your reading device on what app are you going to purchase additional books on?
My answer is: it depends. My wife and I have well over a thousand books on Kindle, but I've got a growing library of Kobo books (from taking advantage of some impressive discount coupons) and almost everything DRM-free I get outside a major ebookstore (e.g. books bought directly from publishers or authors) goes straight into Google Books (they're the best with uploads).
Yes, having books scattered across multiple apps isn't perfect, but it isn't that big a deal, either. Amazon has a significant edge (especially with customer service), but it is nowhere near insurmountable.
