I live in the DFW area, and just off the top of my head I can think of 6 or 8 B & N outlets within a 10 mile radius of my house. I wouldn't be at all surprised to see some of them bite the dust, although I hope the chain doesn't die altogether.
I was about to say that B & N is my favorite place to browse, but actually I'd have to say that goes to Half Price Books, which has about the same number of stores that B & N has. And they are always busy. They are even starting to sell new books there, often at a significant discount. They had the final Wheel of Time novel for sale at 20% off on release day. I wonder how much chains like that are eating in to Barnes & Noble's sales.
