Laptop

The first true laptop was the GRiD Compass 1011, designed by Bill Moggridge in 1979, and released in 1982. It was enclosed in a magnesium case and introduced the now familiar clamshell design, in which the display folded shut against the keyboard. The device could also run on batteries, and was equipped with a 320x200-pixel plasma display and 384 KB memory. It was not IBM-compatible, and it was priced at a steep $10,000.
