Presumably they wish to consolidate all ebooks in one place. Personally I don't understand why anyone wouldn't consider calibre to be a far more able and flexible central repository, but this is irrelevant to the point I was trying to make. Once again, based on what I read at MR, those who like emailing books seem to prefer to email MOBI rather than the MOBI/KF8 dual format Amazon also support.

As an aside, to speak personally, although I managed to successfully email a dual format MOBI/KF8 to Amazon, nothing I did persuaded the Amazon server to download the KF8 part to Kindle4Android on my phone. I must have been missing a vital incantation or ingredient (eye of newt, maybe). I gave up trying quite quickly, life's just easier with EPUB in my world.

You misunderstood my comment. I was not referring to retrofitting old devices I was referring to Amazon's decision not to allow KF8 to be emailed as a personal document. I suspect many more would have been weaned off the primitive MOBI format by now if Amazon had decided to do so. Obviously not everyone because some people hang onto their old devices until they give up the ghost.
