Steve Jobs once said:

"It comes down to trying to expose yourself to the best things that humans have done and then try to bring those things in to what you're doing. I mean Picasso had a saying. He said, 'Good artists copy, great artists steal.' And we [at Apple] have always been shameless about stealing great ideas."

While Jobs may have slightly misquoted Picasso to PBS' "Triumph of the Nerds" in 1996, his point was that the Macintosh was an iteration of previous computers and technology, rather than a completely new innovation.
