E-commerce leader Amazon is prepping for the release of its new tablet with a site redesign that could shake up the world of online shopping. Not only is the new look optimized for tablet shoppers, but it also attempts to drive users towards digital content, as Amazon has expectations of selling more of that content with the holiday release of the tablet. This big change in its site means that Amazon seems to be betting on tablet-based shopping and content consumption as the future of e-commerce. Their success could have a huge impact on online shopping behaviors.
