Pedion

The Pedion was the world’s thinnest (18 mm) and lightest (1.45 kg) A4 notebook computer when it was announced by Mitsubishi Electric in September 1997. It featured some of the world’s most sophisticated technology to realize a slim 6.2-millimeter LCD screen, a low-profile 3.6-millimeter keyboard, a thin 6.5-millimeter lithium-polymer battery, and a magnesium diecast shell with a thickness of only 1.0 to 1.2 millimeters.
