Apple would not exist had Jobs not had the insight to turn Wozniak's hobby into a marketable product. Indeed he had much help to grow the company, but that help is a commodity far easier to find than a man like Jobs who could spy potential and lead those resources toward his vision.

In his early days, Jobs was a terrible manager, a tedious perfectionist, a narcissistic autocrat, and an emotional child - yet he had the passion, charisma, and vision to see potential and make it happen. Because of that, all his negative qualities become charming quirks instead of causing him to be kicked to the curb for good at 20. He was probably rightfully booted from Apple for those characteristics, and it was far easier for him to tame those demons than it would have been for Wozniak to take on Jobs' charm.

There's a reason there is only one Jobs and one Apple, yet thousands of Wozniaks and still one Apple - Jobs is a rarer and more essential talent. Wozniak was quickly replaced when he became disengaged - Jobs still can't be.
