I was really interested after this comment if only because Calibre really is an iTunes for ebooks: 1. It has updates ALL THE TIME 2. It has a billion features and I only need one (moving books to/from the device) Unfortunately, after looking over the feature list and realizing that it's for Linux, I realized that this is more of a replacement for Books on OS X -- a local ebook reader.
