Contrast is SUPERB
The contrast on that Kindle screen is the best I've ever seen. Its even better than on my PC. It makes my Sony PRS 900 screen look like the stone age.
I just purchased that Sony PRS 900 in December, 2009 for $ 400. Now its made obsolete by a $ 180 purchase of the Kindle 3 with a case.
I assume in 12 months the K4 will make the K3 obsolete. We really only pay for 6 months use when we buy one of the eReaders. By 12 months they become WORTHLESS.
