The Pedion was a subnotebook created through a collaboration between Mitsubishi Electric and Hewlett-Packard in 1998. In the same year, Hewlett-Packard released a rebranded variant under their HP OmniBook lineup, calling it the OmniBook Sojourn. The name "Pedion" derives from the Greek term pedion (πεδίον), which translates to "flat" or "plain".
Measuring only 19 mm in thickness, the Pedion held the record as the world’s slimmest notebook, even thinner than the 2008 MacBook Air, which was 4 mm at its slimmest section. Its specifications included a 233 MHz Pentium MMX CPU, 64 MB of RAM, and a 1 GB hard disk.
The Pedion introduced the island-style keyboard, incorporating scissor-type switches characterized by low key travel and flat keycaps separated by a plastic frame—a keyboard design that became widely adopted nearly ten years later.
Manufacturing was discontinued after Mitsubishi pulled the product from the market citing "mechanical problems."
