Since the items are presented online, there is no need for packaging - except for the obvious fact that the manufacturer has one distribution model per item, typically. Once manufacturers are requested that their goods come in 2 models (which is often true of wholesale/retail items -Sams Club vs Wal-Mart packaging) then the manufacturers will acknowledge the need for different product packaging based on vendor influence. Considering the cost savings associated with eliminating the print and plastic, this should be a win-win for consumers and retailers alike. Adoption of this model is imminent and rational.
Security is the other element of the packaging, and is a rudimentary method in theft(loss) prevention. Since the only way to steal from online retailers is via XSS, SQL injection, cookie tampering, identity theft and other methods of vulnerability exploitation, it seems obvious that the costs savings transferred to the online retailer should be used to thwart online theft, in the form of Web Application Firewalls, Network Security and sound application development practices internally.
Product models are evolving with their distribution models, and the world welcomes a paradigm shift from the current physical markets need to present and secure goods physically to customers to the new market and the need to present and secure goods without pollution, waste and added costs that are passed to the consumer.
I welcome the change, and hope the manufactures realize this can make a difference that generations will benefit from - abolishing waste and pollutants that provide no true benefit to the sales model.
