I got a bunch of free books via bookfunnel, and most of them include the new kindle epub format in addition to the standard epub format. My question before I import them into my library is, is there any substantive difference between kindle epub and standard epub? If there isn't any difference, then I would see no point in putting the kindle epubs in calibre, and just sideload them manually if I really want to use them on my fire tablet.
