Whether or not you like Apple, to argue Steve Jobs was not a Titan of Technology is foolish.
Apple was a failing company before Jobs took it back over in the 90's (?). He revolutionized 3 major markets: Portable Music, Smart Phones, Tablets.
Yeah, there were products for each of those before, but other than the Walkman and Blackberry, no one gave a shit about any of them. Did he and Apple make the most advanced products? No, but he did manage to create high-tech products that average people could relate to and understand, which is a significant achievement.
It's a shame when anyone dies, and Steve Jobs is no exception, but Apple will do just fine without him. I believe Jobs was able to create a culture at Apple this time that will continue to make products that consumers love, even without him.
