An anonymous reader shares a report: Apple CEO Tim Cook delivered the commencement address at the Massachusetts Institute of Technology Friday, and he couldn't help taking a swipe at a rival. In a section of his speech describing his search for answers and tough decisions in college and beyond, he admitted turning to a Microsoft computer. "I went to grad school at Duke, looking for the answer," Cook said. "I tried meditation. I sought guidance and religion. I read great philosophers and authors. In a moment of youthful indiscretion, I might even have experimented with a Windows PC. And obviously that didn't work." The line got a hearty laugh from the crowd.
