Osborne 1, the First Laptop Ever
The Osborne 1 was the first commercially successful portable microcomputer, released on April 3, 1981 by Osborne Computer Corporation. It weighed 10.7 kg (23.5 lb), cost USD$ 1795, and ran the then-popular CP/M 2.2 operating system. The computer shipped with a large bundle of software that was almost equivalent in value to the machine itself, a practice adopted by other CP/M computer vendors.
