Steve Jobs and Steve Wozniak were a team, and Jobs would regularly tell people their work was "shit" if it didn't make sense.
Apple traditionally burned out its talent, and is no longer structured to follow Jobs original vision. There is a lot of goodwill with the users, but just like Sony/HP/IBM/Microsoft/Sun it can't last forever. The process-people entrench themselves, and ruin everything... just as Jobs predicted. =3
What does Woz have to do with it
Jobs often set project goals well beyond current technology, and the people around him were responsible in actually getting product out the door.
Naively asserting stuff is "Shit" and firing people that disagree with you on superficial deliverables is not a difficult role. However, teams pushing new technology out to the general public is challenging, and even Apple gambled on the wrong product at times.
Jobs was right about a lot of marketing trends, but also was a controversial character. I would recommend watching the classic interview just prior to his return to Apple, as it aged well... =3
