Microsoft played a significant role in the mobile division when it had access to Nokia’s patents and technology but eventually gave up on the project, ceding control to Google in the mobile ecosystem. Satya Nadella, Microsoft’s CEO, continues to express regret about this decision and believes the company missed the potential of mobile devices and their long-term impact on the industry. In an interview, Nadella acknowledged that Microsoft’s exit from the mobile business was a significant mistake and that the decision could have been handled better. He took over as CEO in 2014 and decided to exit the mobile business, a decision he now regrets. Microsoft’s past leaders, including Bill Gates and Steve Ballmer, have also expressed regrets about this move, especially as they witness the success of Apple’s iPhones. While Nadella has made positive changes during his tenure at Microsoft, the company’s exit from the mobile segment remains a major regret. Microsoft has since made deals with Samsung and developed apps to connect smartphones to Windows PCs, but the future of its involvement in mobile devices, including the Surface Duo lineup, remains uncertain. Despite their successes, Nadella and his colleagues will always carry the regret of giving up on the mobile business too easily.
