I agree, he doesn't look even remotely angry. The guy asking the question sure did, but Jobs looked pretty relaxed. And his response was amazing. No wonder he could create the Reality Distortion Field ;).
It is the same struggle that Woz had regarding the Apple II. Woz was looking at all of the success the Apple II had and was still having and Jobs knew it would not last forever and he had to create the next thing and that that is where the company has to put time, money, and attention.
