You said -- "I thought Jobs' keynote address to be very impressive."
I was reading the blog notes by those attending the keynote speech -- at the time it was happening. And one blogger said "RDF in full force"
So, what I think you were seeing is what makes Steve Jobs so good -- that his RDF (Reality Distortion Field) works so well and he makes excellent presentations. So, for sure, it was the *highest level* I had ever seen the RDF at.
