This is excellent for purchased books. Downside is that is does not appear to allow you to read converted PDFs, DRM-free mobipocket books, or other content you have transferred to Kindle, which is a bummer. Very nice iPhone reading experience, clean UI, easy to setup, and fast downloads (even on 1G iPhone).
