Try this on for size AR postal boxes.

Although Augmented Reality has still to prove it's usefulness as an everyday application, the Priority Mail Virtual Box Simulator is a great instance of technology being used to make life easier for users. You can go online and place a virtual postage container around your object and know your postage price straight away. I think this is a great example of making a new technology accessible and easy to use. eBay shops must love it in America.
