Actually he didn't say much, but what do you expect from campaign speeches, and from speeches in general.
Not much new to what he said
One thing was interesting was the call for nuclear disarmament, not only from Iran but worldwide. I wonder if he keeps this up during his presidency.
At least he can pronounce "nuclear", so no more "nukular" weapons in "Isreal" with the next president (McCain can also do that, I suppose)
On the whole, he's really a great speaker. Dubya's problem as a speaker (aside from his sloppy pronounciation and general daftness) was that he always tried to be Churchill.
Churchillean pathos requires a real man like Mr. Churchill was to deliver it convincingly. Just having a great backround and an aircraft carrier (for example) does not do the trick.
Obama, while not really imitating Dr. King, has some similarities.
Instead of sticking to the classical roman approach to a speech, his way of speaking is more pastoral, almost musical with recurring themes and refrains.
