Your PDA connects to the local infrastructure and asks it to build a custom GUI
You have complete, secure, optimized access to local devices and your private resourcesProject @ Berkeley: Imagine…
of the above!
People and their machines should be able to access information and communicate with each other easily and securely, in any medium or combination of media - voice, data, image, video, or multimedia - anytime, anywhere, in a timely, cost-effective way.
George Heilmeier (CEO of Bellcore)IEEE Communication Magazine, 1992
The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it... the idea of a “personal computer” itself is misplaced... the vision of laptop machines, dynabooks and “knowledge navigators” is only a transitional step... a new way of thinking about computers, one that takes into account the human world and allows the computers themselves to vanish into the background.
