While the Fire HDX tablet was released last year, it's still in some ways a current tablet which makes this offer very tempting. This tablet has only a single camera but it does have a 2.2 GHz quad-core Snapdragon 800 CPU with an excess of RAM, adequate storage, and great sound. It's also going to be getting an update to run the latest FireOS Sangria, removing any temptation to upgrade.
