"In an ideal world, the computer will become invisible. The ultimate will be when almost any object that we buy, no matter how inanimate, will contain an embedded processor that will enhance its function. A coffee cup, with embedded sensors and processing, could monitor how many cups of coffee you have drunk that day, along with the amount of milk fat and sugar, and then upload this information into your personal health maintenance program. The program might also tell you if you are drinking too much caffeine."
Roy Want, manager, embedded systems division at Xerox PARC
