So I've been using a Kobo Aura HD. Recent problems with them were my last straw, and I'm being given the early Christmas present of a Kindle Fire HDX.
I have a large Calibre library (1300+ books) and they are ALL in epub format.
Is there anything I have to do to get ready to use them with the HDX, besides doing a mass conversion? Do I convert to mobi, or AZW3?
Is there a step by step guide anywhere to how to do this painlessly? Thanks!
