Many companies built personal computers. Only one built the Mac. Jobs would have found someone else. Being able to make things is not as common a skill as knowing how to make things great.
My impression was that Woz developed apple 1(which gave apple some funds) by himself(with jobs only encouraging/pushing) and developed a very large of the apple II(which made apple a multi million dollar company) and then not much else. which was one of the first personal computers and was transformational(helping introduce personal computers into the world including a wide variety of clones. Jobs was the team head who designed the first mac(which was transformational in its own way-one of the first gui ) personal computers). At least according to foklore.org a decent number of the brilliant people working for apple on the mac and other projects were there in a significant part because they fell in love with woz's work.
