I assume he would say the same things I would hear him say in meetings where the installer team would show him the lastest versions of the application. A special memory comes from the time where the installer progress bar starting going in reverse. The installer and mail teams received a lot of abuse. It took a special person to stay motivated given all of the challenges they faced and the feedback they got from SJ.
As a customer (my personal computer/display/phone/etc spend with Apple over the past 20 years or so: $25k+): I would prefer having someone in charge who can tell/understand/sense and say that something is clearly not good enough and then actually getting it solved. Tim Cook does not strike me as that kind of guy.
