Goldman Sachs Wireless NYSE Handheld Device

This project outlines a very interesting approach to designing an information appliance - the method adds novel digital functionality to existing physical activities. The idea was to 'bring the technology to the project gently'. I am currently (finally) reading information appliances and beyond so this is sort of timely. A good review can be found at uidesign.

Also on the DIDI site is:
