i went for the nook color, rooted it and now i have a full fledged tablet with eReader.
love it and the price of $250 works too for a mini iPad (7"), basically
gonna slam froyo on it and eventually honeycomb, when that comes out
i have the kindle reader app on it for all my kindle stuff as well as the B&N reader for epub stuff..
excellent deal, imho
