In 2007, then-Microsoft CEO Steve Ballmer famously and publicly laughed at the launch of Apple's first iPhone. ⁠ ⁠ In an interview with USA Today just days after the January 9, 2007 keynote, Ballmer dismissed the iPhone's chances of success, citing its high price and lack of a physical keyboard. ⁠ ⁠ History, of course, proved Ballmer's assessment to be entirely wrong. ⁠ ⁠ The iPhone, and the app-based touchscreen smartphone design it pioneered, went on to revolutionize the mobile phone industry.
