What is "pedion"

n. (context crystallography English) An asymmetric triclinic crystal form that only has one face.

The Pedion was a subnotebook computer developed by Mitsubishi Electric with Hewlett-Packard in 1998. At 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 means "plain", "flat", "field".

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