“The MacBook Air, unfurled [yesterday], might be the thinnest notebook on the market today, but it’s not the thinnest of all time,” Michael Kanellos reports for CNET.

“That distinction belongs to the Pedion, an ill-fated notebook developed by Mitsubishi and Hewlett-Packard back in 1997.The Pedion measured 18.4 millimeters thick, which comes out to 0.7244 inch thick. Although the Air gets to 0.16 inch at the thinnest point, the Air is 0.76 inch thick at the beefiest portion, making it minutely thicker. Mitsubishi released the Pedion in early 1998,” Kanellos reports.

“The Pedion, however, wasn’t exactly the paragon of quality or value. The $6,000 notebook came with 64MB of memory and a 1GB hard drive. The notebook came with a magnesium case to make it sturdy. Even with that, though, consumers quickly reported mechanical and other problems. Mitsubishi subsequently withdrew the notebook from the market,” Kanellos reports.
