Today marks the debut of two features we've been waiting for since Amazon first announced its new Kindle Fire line lo so many weeks ago. Goodreads and Second Screen integration will be rolling out to Fire HD and HDX owners over-the-air in the next couple of weeks - or you can just go to Amazon's site and download Fire OS 3.1 right now. Goodreads brings social book reading features to the tablet, so you can rate and review books and find out what your friends are reading. Also, good news for those who like showing off their virtual bookshelves - you can actually import all of the print and e-books you've bought from Amazon over the years. Second Screen, meanwhile, lets you "fling" shows from your Fire to Samsung TVs and sets with a PS3 attached (PS4 support is coming before year's end).
Also new for OS 3.1 is added enterprise support, Cloud Collections for organizing content off-device and voice diction.
