"I think you are confusing Wozniak with Steve Jobs
Actually I'm not. Woz was an innovator, Jobs was a marketing wizard.
The design of the Apple II disk interface is an example of what I am referring to. It was cunning in that it avoided the use of an expensive chip, but it was not optimum as it occupied the entire CPU capacity during disk transfers by performing in software all the low level operations that a floppy disk interface chip would have done silently without burdening the CPU. Consequently it was great innovation but not brilliant engineering.
