"All of my working-class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it," he said at a Stanford University commencement address in 2005. "I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out."
Wozniak's homemade computer drew attention from other enthusiasts, but Jobs saw its potential far beyond the geeky hobbyists of the time. The pair started Apple in Jobs' parents' garage in 1976. Their first creation was the Apple I — essentially, the guts of a computer without a case, keyboard or monitor.
The Apple II, which hit the market in 1977, was their first machine for the masses. It became so popular that Jobs was worth $100 million by age 25. Time magazine put him on its cover for the first time in 1982.
During a 1979 visit to the Xerox Palo Alto Research Center, Jobs again spotted mass potential in a niche invention: a computer that allowed people to access files and control programs with the click of a mouse, not typed commands. He returned to Apple and ordered the team to copy what he had seen.
It foreshadowed a propensity to take other people's concepts, improve on them and spin them into wildly successful products. Under Jobs, Apple didn't invent computers, digital music players or smartphones — it reinvented them for people who didn't want to learn computer programming or negotiate the technical hassles of keeping their gadgets working.
