Believe it or not, I use one of those Nook Simple Touches from nineteen dickety two. Cause you can change the battery easily, I got it for super freakin' cheap and with a light source it's perfectly fine. I just realized though, you're asking for programs. That I cannot tell you. I just use whatever is simplest on my lappy. I don't read on it often, and when I do it's typically for PDFS, which open in the browser. Eh!
