Do you know who Douglas Englebart is? Your reviewer did not, to his everlasting shame. Englebart invented the device we know as the mouse. When he introduced the little gizmo at a demo in San Francisco in 1968, he also presided over a videoconference between San Francisco and Stanford University. Englebart's story, as well as a whole slew of links to information about him, are all available at www.cnet.com/techtrends/ (click on digital culture).
