Jeff Bezos and company announced the latest version(s) of the Kindle line yesterday. The Kindle Fire HDX tablets, one with a 7-inch 1920×1200 screen and another with an 8.9-inch 2560×1600 display, are absolutely gorgeous, and powering all that screen real estate are 2.2GHz Snapdragon 800 processors and 2GB of RAM, making them significantly more powerful than the last generation of the Kindle. But the feature that Amazon is most excited about is the new "Mayday" button, that promises real, in-person tech support via live video chat on your device within 15 seconds of being pressed . Truly unique and intriguing. Powerful and beautiful, they are sure to be very hot sellers this holiday.
