" Since Amazon hasnt updated anything about their typography since 2009 I wouldn’t hold my breath."
That is actually not true - http://www.onemanandhisblog.com/archives/2015/01/bookerly_am...
Oh and this - "Speaking of highlights: Amazon has no graceful option to update books. Updating a book, in Amazon’s world, is the digital equivalent of handing you a new book, then burning your old one. Hope you didn’t have any notes or highlights in there." Hey that's actually not true. I beg the author to please provide examples and scenarios. Amazon goes to great lengths to not impact the reader by erasing their notes.
