Pedion

The Pedion was a subnotebook computer developed by Mitsubishi Electric with Hewlett-Packard in 1998. At 0.7244 inches (1.84 cm) thick, it was the thinnest notebook computer in the world, even thinner than the "Macbook Air" (although the Apple equivalent was 4 mm at its thinnest point), released nearly ten years later.

The Greek word, pedion (πεδίον) means "plain", "flat", "field".

Mitsubishi ceased production and withdrew the notebook from the market due to "mechanical problems".
