What do you carry on your person now? Probably at least keys, identification, money, and a watch. Quite possibly you also carry credit cards, a checkbook, traveler's checks, an address book, an appointment book, a notepad, reading material, a camera, a pocket tape recorder, a cellular phone, a pager, concert tickets, a map, a compass, a calculator, an electronic entry card, photographs, and perhaps a loud whistle to summon help.
You'll be able to keep all these and more in another information appliance we call the wallet PC.
