I'm not sure what you were disagreeing with, but I have to disagree with your disagreeing because if 5/11 people crashed the thing in an hour, it's completely unusable for many people, me included.
Also, the statement about Ubuntu being less stable than debian testing. I don't know the GPs specific instance, but Ubuntu has basically made debian a usable desktop.
As I understand it anyway, I wasn't using Ubuntu Desktop by the time the pulseaudio thing happened.
