Steve Jobs, the mastermind behind Apple's iPhone, iPad, iPod, iMac and iTunes, has died, Apple said. Jobs was 56. "We are deeply saddened to announce that Steve Jobs passed away today," read a statement by Apple's board of directors. "Steve's brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives. The world is immeasurably better because of Steve. His greatest love was for his wife, Laurene, and his family. Our hearts go out to them and to all who were touched by his extraordinary gifts."
