While we now take a computer mouse for granted, fifteen years ago there was still a debate about what would be the ultimate pointing device. This program reviews several options including the PowerMouse, the MousePenPortable, Wacom's Cordless Digitzer, MicroSpeed's PC-TRAC trackball, the first optical mouse PCMouse III from Mouse Systems, the OmniMac Ultra, Elographics MonitorMouse, and Mac'n Touch and the UnMouse from MicroTouch. Originally broadcast in 1990.
