CNBC's Jim Goldman sat down with Steve Jobs after Tuesday's "Let's Rock" event to ask some follow-up questions. While the interview focused on Music and Macs, Mr. Goldman did inquire about Mr. Jobs' health off camera -- which was described as good, even if he could stand to gain 10 or 15 pounds. Mr. Jobs declined to comment on the new Microsoft ad with Bill Gates and Jerry Seinfeld, but the look on his face was priceless.

Asked about his health, Mr. Jobs said, "I'm doing fine, really." Mr Jobs offered that all the fuss about his health was coming from "hedge funds with a big short position in Apple." It was said in passing, and Mr. Goldman didn't characterize the comment as a hand grenade tossed at anyone specific on Wall Street.

The video interview provided some insights into why Apple returned to the vertical format iPod nano in addition to probing about recent missteps at Apple. Mr. Goldman also asked about the momentum of the Macs, and Mr. Jobs suggested that the Mac has reached the "tipping point."

Finally, the interview is notable for Mr. Jobs' reaction to the new Microsoft ad with Bill Gates and Jerry Seinfeld -- not for what he said, but for the look on his face.
