First statement is completely up for debate. Jobs did continue without Wozniak and he failed every product in the next 18 years and spent millions of dollars. Not something founders here can emulate.
The Mac failed?
NeXTSTEP failed, when it's running the millions of Mac, iPhone, iPad, iPod touch, and Apple TVs today?
Pixar failed?
Jobs' record has more successes than Wozniak's.
