I have both the Nook black and white and the Nook color. I love the wi-fi. I have an e-card at the library (not here in FL)(check with your local library) and I can download lots of books, free. I can keep them for 2 weeks and then, if need be, I can borrow again, I can read the black and white in the sun and I have a backlight on my color Nook. Smashwords is good, but not all hat versatile
