The newest models, the Nook Glow, Kobo Glo and the just about to be announced new Kindle (though I presume since you already own a Sony you'll prefer an epub e-reader) all have the added extra of a front-lit screen that you can turn the light on for reading in low lighting/dark.
Thank you, I'll do a little research. I do like my epubs though. Like to check out a lot of library books. My old rca 1100 has a back light to it, I just wish I could find more books to put on it.
