Apple Macintosh computer, model M001, c 1984.

UNITED STATES — APRIL 06: Apple Macintosh computer, model M001, with keyboard and mouse. The Apple Macintosh was designed by Steve Jobs to be as ‘user-friendly’ as possible. Jobs wanted to produce an ‘appliance computer’ that clients could unpack, plug in and start to use with very little computer knowledge. It was also designed to use a graphical display rather than the standard text-based display previously used. The Mac was an instant success and continued to be popular as Jobs had ensured that plenty of computer software had been designed for use with the machine. (Photo by SSPL/Getty Images)
