The 7-inch Kindle Fire HDX is a surprisingly sexy tablet. For $230, the same price as the Nexus 7, the Fire HDX comes with the same beautiful screen (1920x1080), but a much faster SoC (Snapdragon 800 vs. Snapdragon 600) and significantly more battery life (about 11 hours vs. 9) -- and the HDX is smaller than the Nexus 7. If your primary purpose for owning a 7-inch tablet is media consumption, the Fire HDX really is superb. The new Mayday function, which lets you call Amazon's excellent customer service department with a couple of presses, is truly revolutionary as well.
