EBook Standards
Of course, they wouldn't be publishers if they didn't also lust after robust DRM measures, which might explain why they're not roundly supporting the readily available EPUB format. It has DRM options, but perhaps they're not gnarly enough for the dudes responsible for bringing us the psychological horror of the Twilight series. We still don't like the suggestion that the people, Amazon primarily, who popularized this market should just open it up out of the goodness of their own hearts -- maybe we would if publishers ever showed themselves capable of doing similarly noble things.
Really, that about sums it up. If they want a standard, what's wrong with ePub?
