When I visit local bookstoers I avoid the computer sections. I do not want my mood to be ruined - these sections are reduced by the factor of three or four and have old books gathering dust. No new books there.
That may have more to do with the fact that online booksellers can beat any local bookstore on price and they deliver to your door free of charge for orders over $25 dollars. Bookstores in general are being killed off by online book sales. That's one of the reasons they sell more than just books now, e.g., coffee, food, deserts. They know most people just come there to browse with little intention of actually buying a book.
