I get the model where you go into BestBuy, look at the TV, listen to the stereo and then purchase online.
But what does browsing for the book on the shelves get you over searching Amazon.com? You still get the same 'about the author' and plot taglines on the back...
Maybe there's some nostalgia that people enjoy walking through the stacks and prefer to read via eReader. For those people, the bookstore will die anyhow because no purchase will ever be made via the bookstore.
These bookstores need differentiate themselves from eReader providers just like movie theaters differentiate themselves from watching at home and Netflix. Movie theaters provide a service you don't have at home (a 100ft screen and a huge wattage sound system, and stadium seating).
Bookstores need something as well, book clubs (how do you keep people from joining the club that purchased the book via amazon), social gatherings, something...
All of these businesses died because the physical location couldn't differentiate itself from the delivered direct to home version:
*Video Rental shops
*Computer stores (CompUSA etc..)
