My Kindle receives correctly the ebook (in the documents folder the file has a .azw extention) and it appears fine (also with cover). I know that MOBI is an old format. What are the main differences from this format (after I send it to my Kindle by e-mail) and a newest format like EPUB2 or KFX? I have seen that in these ebook converted in MOBI format I can correctly change fonts, layout, magins, page orientation, etc...

Thanks

Well...I mean, if it's working for you and you're happy, does anyone else's opinion really matter?

Myself, I can't be happy with Calibre (or any) old-style MOBI output, any longer. I can't live without typography and hyphenation, and the KF7-brand of MOBI that Calibre creates doesn't have that.

To emulate it, via Calibre, you have to use JHowell's plugins for hyphenation and all that. I tried reading some PG MOBis that were clearly done with Calibre and my brain refused to accept them. I like the kerning/tracking, hyphenation, etc. that you get with properly-formatted and processed Amazon files, whether those are KFX, "mobi" AZW, or whatever.

If you don't buy eBooks from Amazon, or see the files that they process, I'm really not sure how to describe what the difference is, in any meaningful way. I mean...if you've nothing to which to compare it, you don't see the difference and why would it matter to you?

ePUB2 has been accepted at KDP for...hell, 10 years now or damn near. It's reprocessed into whatever format they're serving, so now, I honestly don't know if they're still serving AZW or KFX or...? Jhowell will know. (JHowell Knows All...)
