What would you call a device that has a screen, a keyboard, storage for personal information such as contacts, email, documents, the ability to play audio and video files, some games, a spreadsheet program, and a communications capability? Sound like a personal computer? How about “mobile phone”?
A mobile phone has substantially all of the computing capabilities desired by a large fraction of the public. Why then would someone want to go to the trouble of installing and maintaining a personal computer (PC)? The PC has a larger keyboard and screen, a larger storage capacity, can play more sophisticated games, and has a faster communications capability.
This is a plan for building an appliance into which a mobile phone plugs and that extends the phone’s capabilities without requiring the consumer to become a system administrator or be aware that he or she owns more than a phone. In the rest of this document we will call the new device “The Appliance”.
