Living Digitally published their review of the Kindle on the 21st.

The Kindle's navigation system is reasonably good, though it takes getting used to. The inclination is to scroll up or down to get at previous or next pages which doesn't work (and rightly so — this is supposed to be a book!). And the back button doesn't work like a browser's back button. In other words, back doesn't take you to the last page you looked at; rather it seems to take you to the last navigation juncture, or menu. Although this is confusing, once you understand how it works, it's pretty efficient.

The reviewer also supports the use of DRM and lists the type of books they expect to read on the Kindle. The review is well worth the time to read..
