Interesting to know about Tesla and Edison. I've always seen somewhat similar parallel between Jobs and Wozniak. For all his greatness, I always see Jobs as an overrated CEO and Wozniak as underrated geek.
I fail to see how Wozniak is underrated. On the opposite, the media likes to pick up whatever he says about today's technology and portray him as the real genius overshadowed by “marketer” Jobs, although Wozniak's last contribution to the field was two decades ago and he has no relation to Apple's success as we know it today. He deserves praise for what he'd done but I'd argue his contributions are rarely, if ever, underrated, and often the opposite.
Saying that Steve Jobs shipped frequently than Wozniak is like saying the manager of a software team ships more frequently than the programmers who wrote it, since he is the one who sends out the 'release notification email'.
Actually what he's referring to is that Woz basically made the Apple 1, made the Apple 2, and then, having produced two once-in-a-lifetime masterworks, essentially retired.
Jobs, though less technically useful on any one hands-on task, never retired even after getting rich. He just kept shipping, ultimately an order of magnitude more projects and a way more grandiose total portfolio.
