But is that with the light on or off? Since they reference a "brilliant white background" when talking about the 25% I'd think it's with the light on. I haven't gotten my PW yet (it should arrive shortly), but in photos I've seen side by side with older eInk devices the screen with the light off looks the same as regular Pearl.
