re: Called it
I didn't spot a teleprompter, but that's not conclusive. I think the latest models use a laser to project text on to the eyeballs. The speech was coherent even if it was rocky at times, and the imperfections make me suspect he was winging it. But I could be wrong.
I know, you're thinking of Obama's gift of oratory. That guy doesn't need a teleprompter, and it'd probably just water down the impact of his speeches. A possible debate between Obama and McCain would be interesting, and not a slamdunk, because some people interpret eloquence as false glibness, while McCain has always gotten points for "straight talk". It'd be a study in contrasts, no doubt about it.
