For those that have the original, does it have a black background option? I find that in the dark the white screen hurts to read after a while (iPad Mini) so I switch between dark and light for night/dim and day outside.
Not AFAIK, but reading on a front-lit Paperwhite is a totally different experience from reading on an actively-lit tablet. I regularly read in the dark in bed, and I have no problem with it at all. When I read on my Nexus 7, I use the inverted scheme, but on the Paperwhite I just set the lighting to a comfortable level and off I go.
