I find it interesting that Amazon purposely designed the Fire HDX to have a blue vignette around the screen. I saw the linked article on why this occurs. However, my Nexus 7.2 does not have any vignetting at all. I realize the Fire HDX most likely has a better, higher quality screen, nevertheless the Nexus 7.2 has a very good screen as far as colors go. So if Amazon purposely chose to use a screen that causes vignetting over one that doesn't, it makes me wonder who made that design decision and why. I doubt the colors on the Fire HDX are that much better than the Nexus 7.2, at least not so much better that it was worth causing the vignetting. After all, the Fire HDX was designed for reading as one of its primary functions, and the included Kindle reading app displays this vignetting more than most apps would. It just seems to me like a really stupid design choice on the part of Amazon.
