Thanks, everyone! I got the new Nexus 7 a few days back and it blew me away. As DoctorOhh wrote, the display with 0% or lower brightness feels every bit like an e-ink display. It's not at all like the LCD displays I have experienced in the past. (I don't read in bright sun light.)
I bought Moon+ Pro and the Calibre Companion, and this duo works wonderfully.
