Adam Osborne invented the laptop because he believed computers would be more beneficial to consumers if they were portable. He set up Osborne Computer Corporation and employed the computer designer Lee Felsenstein before launching the first laptop, known as the Osborne I, on April 3, 1981, at the West Coast Computer Fair in San Francisco.
Initially, the Osborne I was a huge success and retailed for $1,795. The first fully portable computer consisted of a keyboard, a monochrome monitor, two floppy disk drives and free software, all enclosed in a protective carry case.
Unfortunately, due to heavy competition and bad marketing, sales of the Osborne I dropped dramatically, causing the Osborne Computer Corporation to file for bankruptcy protection in 1983.
