You need Snow Leopard to watch the Keynote, (( It does say that in the Requirements)
Come on buddy
I have been ranting about this for a long time now
Come on buddy, I know what the specs say, but did you even try it? Like I said above, it plays in Leopard. I also just tried it in 10.4.11 on a G4 mini with Safari 3 and QT 7.5.5, it plays there too.
You're wrong about this one. No strong arming by Apple, just your strong head, and refusing to even click and try it.
