Pedion (laptop)
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 notebook included a Pentium 233 MMX processor, 64 MB RAM, and a 1 GB Hard disk. 

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

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