I think the truth is eInk varies. I have a good K3 but my brother in law's contrast isn't on his as good as mine. I have two K4s. My first one has horrible contrast and my newest one is the best I've seen on a eInk reader. The PW isn't as bad as my first K4 in background shading but it's close in lightness of text. I'd say without the light I wouldn't be happy with using it.
I can say the PW has become my sole reader. I don't even need to switch around anymore. Even with my K4B's amazing contrast it still can't compete with the PW.
