Amazon debuts Kindle Fire HDX 7- and 8.9-inch tablets, we go hands-on

The slate, like its predecessor, comes in 7- and 8.9-inch configurations - this time out sporting much higher resolutions, at 323 ppi (1,920 x 1,200) and 339 ppi (2,560 x 1,600), respectively. Compare that to 221 and 254 ppi for their predecessors and 264 ppi on the iPad 3; quite brilliant in conference room lighting. For by-the-pool readers, there's also a dynamic image contrast feature, which one exec pulled out a flashlight to demo. The feature works by shifting the display's contrast, rather than brightness, to compensate for external changes in lighting.
