The world lost, today, a genius and a revolutionary. Whether you love Apple or hate them, the company would not be where it is today without his leadership. It is difficult to imagine a world without iPods (which transformed music into a digital format for easy mobility), iPhone (introduce an easy to use and very functional touchscreen cellphone), iTunes (again moving from physical storage [DVDs] to digital) and the iPad (we would more than likely not have a tablet market without the iPad). Of course, there are the Mac computers and Pixar. We cannot forget about Pixar which he started. Disney would not have its blockbuster hits without Pixar. He was a fighter having survived pancreatic cancer and a liver transplant.
Steve stepped down as CEO several weeks ago because he must have known that his time was near. He did the right thing. Apple would have suffered a major hit if he was to have passed away as the current CEO. It was best for him to step down and separate himself from the company which was the right thing to do. Apple will continue to survive but nonetheless it still suffers a big loss.
