I bought the refurbished model because it was considerably cheaper and was so happy with it my brothers and I bought the new Nook Simple Touch for my mom's birthday. (She never would have bought one for herself) It's black and white but has a touch screen, is so lightweight and easy to use. She's still getting used to it but really likes it, especially the adjustable font.
I'm also grateful for all the links people have provided to great deals and helpful tidbits for e readers. I'm amazed at how much there is out there and I'm finding more every day! Thank you to all, I really appreciate it. Now I just need to get to it and read more. It sure makes those piles of books to be read a lot smaller!
