Since all of the features in Fire OS 3.1 were already announced, there aren’t any surprises. Still, the software will help make the overall Kindle Fire tablet experience a better one.
For example, there’s deep in-content integration with Goodreads, making it easy to capture and share quotes with others on the social reading service. You can also see what Goodreads friends are reading or share a book rating. And every Amazon book purchased — digital or print — can quickly be imported to a Goodreads account.
Of course the Kindle Fire tablets are more than book readers; they’re video content consumption devices. And the newest software includes a Second Screen feature: You can “fling” video content from the Kindle Fire tablet to an HDTV, similar to Apple’s AirPlay and Google’s Chromecast functions. Amazon says Second Screen works with Sony’s PlayStation 3 and Samsung televisions; support for the PlayStation 4 is expected by year end.
