Tim Cook was on Good Morning America yesterday, talking about the new iPhones and Apple Watch. The whole thing was very watchable, but two notes:

First, it’s interesting to watch Tim doing a somewhat spontaneous interview. Granted, he’s practiced his talking points and knew the questions going in, but he’s gotten terrific at sharing his enthusiasm with just the right tone, not an easy thing to do.

And second, jump to about 3:05, where Robin Roberts asks Tim about the cost of the new iPhone. Tim’s response is both deft and interesting.
