Steve Jobs is back! It’s his first appearance at an Apple event since last year and his first period since he returned from medical leave in June.

“I’m very happy to be here today with you all. As some of you know about 5 months ago I had a liver transplant, so I now have the liver of a mid-20′s person who died in a car crash. I wouldn’t be here without such generosity. I hope all of us can be as generous and become organ donors.”

iPod nano gets it’s own camera, larger 2.2-inch display, FM radio, a built-in pedometer, in a polished anodized aluminum casing. The new nanos come in 2 models: 8GB for $149, 16GB for $179.
