Amazon peppered its second-gen Kindle Paperwhite announce yesterday with the usual marketing fluff: whiter whites and blacker blacks! But, it turns out, those boasts do have some grounding in reality. E Ink has a new screen tech and, surprise surprise, it's the one that's powering the refreshed Paperwhite's improved readability in sunlight and increased contrast. And the company has some numbers to back those claims too, marking this new "formulation" as offering a 50 percent improvement in contrast over older Kindles, and 20 percent reduction in glare. It's an accurate claim by our estimation, considering we recently had some eyes-on time with the second-gen Paperwhite. Still, it doesn't beat the Kobo Aura HD's screen, but not everything niche can be so nice.
