Steve Ballmer, CEO, Microsoft
"The company I joined 33 years ago was a company focused on software for personal computers. And software is a great skill and will always be a core strength of Microsoft. The PC is an important device, the most productive device on the planet, and will continue to be so. And, yet, for us not only to grow but for us to really fulfill the vision of what we can do for our customers, we've evolved our thinking.
