Obama did do a good job of tying McCain with Bush several times and did appear and sound sufficiently presidential. He held his own on foreign policy despite McCain's contempt toward him.
McCain was much stronger on the economy than I'd expected. Didn't really appear presidential though.
It'll be interesting to see how this plays out over the next few days, but I think it's basically a wash. Though MSNBC peeps are giving it to McCain, at least on points.
