I discovered a feature unlike no other. Today, while trying to search for a book, I noticed a little camera icon next to the search window. I had no clue as to what it would do. I picked up a book, and took a picture of it.
To my amazement, I discovered that by taking a picture, Barnes & Noble system could read the cover, and essentially tell you details about the book - name, author, cost and whether it is available. Awesome application! Just another reason to own an I-Phone.
