Yes but they don't support epub, which is frustrating (at least mine doesn't). Easy problem to fix but it seems the majority of ebooks online follow this format.

What you described is equally true of Kobo, Nook, and pretty much every e-ink based reader. And they all support more formats than the Kindle does.
