Most of B&N's competition is dead -- Amazon ate them. There is still a niche for actual books bought in person, and there is still a demand from consumers to go to a bookstore and do the bookstore thing, drink coffee, peruse, etc.
That niche is probably just in big, educated markets. Like the B&N in Northern VA I used to go to in college is still there. But at a mall in rural Idaho, probably not so much.
