Amazon's pushing out a software update that has a few nice-sounding features like Book Extras, a reading view for Amazon Silk, movie rentals, and personal document storage on Amazon's cloud servers.
Parts of the list sort of read like an assortment of half-measures. Digital copies of textbooks laid out for print instead of Apple's new textbooks. Sharing snippets of text instead of whole books, like the Nook. But even so, it's a nice little haul for anyone using the Fire.
