been strong-armed into using only DRM-encumbered epubs. In any case, I'd be gob-smacked if the DRM weren't crackable. BTW I store all the canonical copies my Kindle books in Calibre on the PC in epub format. Calibre does on-the-fly conversions when loading stuff onto the Kindle and has some plugins that make managing content on the Kindle a lot easier than the, already pretty decent, built-in software.
