Okay, but where do you buy your epubs? IF you buy them?!

For now, if you buy from Kobo store, you can use Adobe Digital Editions to extract the epub in a format ready for Calibre.

Many websites sell epubs, with or without protection. The DRM is never usually that hard to break with Calibre. If you're into that sort of thing.
