Both experience are inclusive, I think.
I must admit I buy most of my computer books at Amazon. This is not only because is more convenient and cheap, but because B&N computer book selection "is a joke" (sorry, but that's the true)
However, when talking about socialization, having fun, going out, nothing can or will replace visiting a mortal brick store like B&N.
Last time was like 3 days ago and I go almost all weekends. I don't buy books every time I go there, but I certainly spend some bucks in the store.
Also even though I can check Amazon reviews online and read some chapters for free, it its more interesting for me to check book covers or book's spine and compare titles myself. That's easier to do (or more fun) with a physical book.
I'm also addicted to caffeine

.. and there is always a Starbucks inside B&N. While not the best Colombian coffee, it is still coffee.
