I don't really care two turds about who uses what browser. I've found that Opera best suits me, and that in comparison, every version of IE since 5 or 6 have just been horribly slow. Nevermind the fact I've fallen in love with Opera's mouse gestures (any other browsers doing that yet?). Never gave FF or Chrome a shot for that reason alone.
As for the vid, it leaves me with the impression that IE sucks, and MS knows it. Just not as much as it used to.
