Apple CEO Steve Jobs has been out of the limelight since he announced in January he would be taking a medical leave of absence from the company, his second in about a year.
Yet Jobs took the stage during the keynote at Apple's Worldwide Developers Conference (WWDC 2011) on Monday to announce new products, including iOS 5, Mac OS X Lion, and iCloud, Apple's new cloud offering.
"If the hardware is the brain and the sinew of the product, the software in the middle is the soul," said Jobs, according to Engadget.
Jobs last appeared onstage at an Apple event to unveil the iPad 2. Additional photos released by the White House in February revealed a glimpse of the executive at an intimate dinner Obama hosted in Silicon Valley for tech leaders.
