Steve Jobs was not only Apple's visionary, he was one of the most important cultural influencers of our time. Apple. Mac. NeXT. Pixar. iMac. iPod. iTunes. iPhone. iPad. Any one of those would be a worthy achievement. All of them, a universe denting one. But Steve Jobs is gone and Tim Cook now helms Apple. He was an operations guy, not a product guy. He didn't dream up the next world-changing product, but he did make those dreams a reality. It would be easy, natural-even, for him to continue in an operational role as CEO, but steadily, over the course of the last two years, he's been doing more than that. He's been taking on a moral role as well.
