Jobs was well known for being biased to shipping over having a perfect product aka "Real Artists Ship". The first version of OSX had non-functional CD writing, from what I recall (fixed in the first update). Siri was released as beta, attenagate, the iMovie and Final Cut rewrites -- these all happened under Jobs.
Thank you - I think people are forgetting such misses as the Cube when Jobs first came back. I remember very distinctly after taking it off the market his comments about not always being able to get it right but they must continue to try and push the envelope. To add to your list btw, he also let MobileMe ship which no one agreed was up to snuff and he acknowledged later by firing the entire team.
