Kindle Fire users can update their tablets. Amazon is bringing a major refresh to the device's operating system that offers improved management of books, newspapers, magazines and apps.
Also added is Goodreads support, allowing users to find and discuss recommended books, plus second screen support for PlayStation consoles and Samsung TVs to bring video on the big screen.
But the most disruptive news from the giant today comes in the form of AppStream, a new service that allows intensive games or apps to play on any device. This, in time, could threaten premium hardware sales and games console launches.
