The very first laptop of History ~ The Osborne 1

                             

 Osborne 1 was the first laptop of history, and despite weighing 10.7 kg and had to connect cable to a 120V power supply, was considered a laptop, but not the first to have been developed because it was the Xerox NoteTaker, but this was the first laptop that was marketed,  in 1981.
