At a dinner with journalists this week in San Francisco, CEA's Shapiro was asked whether he's invited Jobs, who recently returned from medical leave, to keynote the show. Yes, Jobs has been asked, but nobody from Apple has gotten back to him, Shapiro said.Jobs was on medical leave for the first half of 2009 due to complications surrounding his history of pancreatic cancer and he ultimately received a liver transplant. Jobs returned to work in late June and was photographed today on Apple campus.
