I love my NOOK. I agree with all the comments, and would like to add more: All your books are stored in your B&N account, so if your NOOK crashes, all your books aren't lost. When you try to purchase a book that you already own, you get a warning that you have already downloaded it, so you don't double-buy a book. Also, the NOOK has space for an additional drive so you can have even more books at your fingertips.
