Not only could Woz not start Apple without Jobs, he would NOT have started it at all if his friends didn't convince him to join Jobs as a co-founder. He didn't want to leave his job at HP (although he may have left partly because HP refused to develop his ideas), or being anything more than an engineer at Apple even though he co-founded it.

Don't get me wrong -- Woz was certainly an engineering genius, but he didn't have any of the vision that Jobs had for building something great. To Woz it was just something interesting to do. Jobs saw the potential of what Woz was able to create. Those two as a pair were the perfect storm that ushered in a personal computing revolution.
