There are three aspects to information economics:

  • The generation of information
  • The sharing of information
  • The storage of information

Some information, like most of that sent by mouse and joystick, is purely temporary, meant for commanding the computer. Other information is recorded directly, such as keystrokes, then transmitted to others. Other information is captured from the real world (such as in the case of photography), brought to bits, edited and then compressed; the new digital creation is then sent to others.

Keyboards have not been changing much in the course of the last decade; nor have mice, other than to go optical and free us of the monthly ritual of cleaning out the dust rings. Cameras and camcorders, on the other hand, have recently managed to make the leap into consumer digital products and are now considered ordinary to be interfaced to a computer.
