Steve Jobs photos: Then and now

"Steve Jobs' appearance will be key," wrote Piper Jaffray's Gene Munster before Apple's widely anticipated "Let's Rock" special event in San Francisco Tuesday.

Jobs' gaunt features and evident weight loss at his last public appearance - at Apple's annual World Wide Developers Conference in June - drove Apple's (AAPL) stock price down and set off speculation about what might be wrong with him. (link)

In 2004 Jobs had a cancerous tumor removed from his pancreas (see here). Earlier this year he had a second operation to deal with digestive problems stemming from that operation, according to the New York Times (link).

So how did he look today? You be the judge. The photo on the left is from June 9. The one on the right was taken Tuesday at the Let's Rock event.
