It was the apple 2, also designed by Wozniak that really made them famous, not the first one. It was the first personal computer to hit the market that you could purchase and use without some serious technical knowledge, both is software and hardware. So he may not have technically invented the personal computer, but he built one that was actually marketable. And Apple was worth billions within the first years of their existence, so I would say it was pretty influential. Some people may not like Apple, but it's impossible to deny the massive role they played in the early days. And it really wouldn't have happened without Wozniak, he was the technical genius of the group.
