Just one day after the highly anticipated iPhone 4S was unveiled, Apple Co-Founder and former CEO, Steve Jobs, passed away earlier this evening at the age of 56. Jobs, who had battled cancer for years, took a medical leave from Apple back in January and stepped down as chief executive in August because he could "no longer meet (his) duties and expectations."

Jobs was a technological visionary who helped lead the mobile-computing revolution with some today's most popular mobile devices. He pioneered the concept of the personal computer and of navigating them by clicking onscreen images with a mouse. In more recent years, he introduced the iPod portable music player, the iPhone and the iPad tablet -- all of which changed how we consume content in the digital age.
