Steven Sinofsky is head of Microsoft Windows, the best-selling and most profitable operating system with 80% marketshare among all devices, and that's before they launch a new desktop and mobile operating system. Dan Riccio will be head of Apple Hardware Engineering, which make the best-selling and most profitable hardware for phones and tablets, along with best-selling, best-designed, and most-profitable laptops, whether you want to install Windows or run Mac OS X. Interesting to know that in Apple vs Microsoft, Hardware vs Software, the heads of these franchises are both alumni of UMass Amherst.
