On June 6, Steve Jobs made his last public appearance as Apple Computer's CEO to demonstrate new features that would empower and "redefine" iOS devices (iPhone, iPod touch and iPad). Scott Forstall, senior Vice President of iOS, and Jobs took the congregated nerd masses at Apple's World Wide Developer's Conference in San Francisco on a tour of an operating system more influential than the hardware it sits on. The Apple team excited the attendees with astronomical projections, wowed them with the promise of new technology, stole their hearts with long awaited features, then told them the software would be available months after the press release. After four months of development and fine-tuning, iOS 5 will be available for public release Tuesday, Oct. 12.
