I don't own a Kindle so perhaps I'm confused but every spec and report I've seen clearly states the Kindle has built-in fonts, not media embedded. AZW can't do that. It does read the TOPAZ format which supports embedded fonts but all reports say the quality is horrible and it's highly unstable.
I continue to be confused why you harp on the little kobo when the two biggest eReaders in the industry don't do what you want either.
iBooks isn't native. It's an add-on just like txtr or Bluefire. Native means it comes with iOS and iBooks does not come with iOS.
