I also don't believe click-and-mortar sites such as Amazon.com will totally do away with physical retail stores. We still need tactile connections with some of the stuff we purchase, like clothes or cars or book covers (which is why Barnes and Noble Booksellers still thrives).
My prediction is that we will see an evolved hybrid of brick and click, physical stores with online presences. Retailers need to view themselves more than just four walls housing physical inventory to be sold. They need to offer their customers a place to gather to see, experience, and learn about the content and/or brands/ideas they are trying to sell.
Digital distribution is the future, but physical stores are the havens for the human element that many shoppers still seek.
