We treat Barnes & Noble as an entertainment destination. The kids spend time looking through books, my husband loves looking through technical books and then we get coffee and a snack. I love B&N. I like browsing through stuff. I see things I wouldn't have thought to read.
We used to have a Borders close by, but it closed.
I much prefer going into a physical bookstore. The author of "Diary of a Wimpy Kid" opened a bookstore near were I live and I go once a month.
