I have the 3G black and white Nook and the color Nook and love them both. Barnes and Noble has thousands of free books on thier site to download. You can also go into the store and read any book for an hour a day on your Nook. They have free classes to learn how to do different things on it. They have tons of very low cost and free apps for it as well. It does so much, I'm sure the HD is just as wonderful.
