Yeah, here - http://www.tomshardware.com/reviews/...ew,3323-3.html

"According to its spec sheet, Amazon is using the same 6" E Ink 16-level gray scale display (600 x 800 pixel resolution at 167 PPI) on the third- and fourth-gen Kindles. After using the new silver Kindle for a few hours, though, it felt like I was reading text on an inferior screen.

Turning on our microscope, text on the fourth-generation Kindle appears more dithered around the borders. Meanwhile, text on the Kindle Keyboard is slightly sharper, and the black is a little darker.

We called up E Ink Corporation to ask if this was a batch-related issue, and was told that this is most likely due to Amazon choosing a particular grade of display panels. So, while the new Kindle comes at a lower price, the company is probably cutting its costs as well by using a slightly cheaper display."
