An intriguing viewpoint from MIT on how smartphones are changing the dynamic of how we purchase - switching from Internet based, Amazon-like purchases to local buying; due in part to the 'disutility' (in some cases) of buying without sampling the product first physically.
Tries to address why we need stores at all when we can purchase anything from the Internet. Some research showing that as local book stores pop up, online purchases for books in the region drop. Implies that both brick and mortar and online systems will be required to guide increased sales. So does this mean that Amazon will soon start opening stores (as we watch Blockbuster close the remainder of theirs)?
