If we're to see similar consolidation in
the enhanced ebook space in the same timeframe, publishers are going to have to be firm that they will only (or at least primarily) produce standards - based multimedia books.
I don't know what the deal is with this update but I've tried a half dozen different
ebooks that say
enhanced typesetting is enabled and all of them still have awkward
spacing between letters, especially with larger font sizes, and there's not a single hyphen to be seen anywhere with any font size.
