Continuing its transition away from simple e-reader to fully-functioning tablet, the Kindle Fire HDX ($380) packs more power, an improved display, and productivity apps that make it a serious competitor. It features a 2.2GHz quad-core processor that is three times more powerful than its predecessor, with two gigs of RAM and a dedicated graphics card. The display features incredible pixel density (339 PPI), on a nearly nine-inch screen for a better reading and viewing experience. Additional features include a "Mayday" button that lets you call Amazon for help any time, an eight megapixel rear camera, and the ability to connect to 4G LTE.
