Steve Jobs sat down yesterday with CNBC reporter Jim Goldman, the 7 minute interview covers many subjects. Although Jobs didn’t wish to discuss his health on interview he did talk to Goldman off camera.

“Steve Jobs is healthy, was taken by surprise by all the speculation about his health swirling around him after his last public appearance in June, and says while he could ’stand to gain 10 or 15 pounds,’ he’s doing just fine,” Jim Goldman reports for CNBC.

“I agreed not to address the speculation about his health on camera, because Jobs didn’t want to go there. As long as I could ask a passing question about his health off-camera, but on the record after the interview, I’d be satisfied. Apple agreed,” Goldman continued.

In the interview itself Goldman quizzed Jobs on the lack of Mac announcements at the event, Jobs rebutted by explaining that the event was music focused.

Jobs also admitted that customers preferred the older iPod nano and thus reverted to the vertical form factor.

“It was very clear to us that customers preferred the vertical form-factor for their iPods. That was the first- and second-generation,” Jobs said. “The third-generation we went to a squarish design so we could fit in a really high-res screen. And we managed to do both in this [fourth-generation iPod nano].”
