Microsoft CEO Satya Nadella acknowledges the mishandling of the company's exit from the mobile phone business and regrets not reinventing the category of computing between PCs, tablets, and phones.
Microsoft faced a series of missteps in its mobile strategy, including writing off $7.6 billion related to the acquisition of Nokia's phone business and the discontinuation of Windows Phone.
Former Microsoft CEOs Bill Gates and Steve Ballmer also expressed regret over the company's mobile-related decisions.
Despite these setbacks, Microsoft has shifted its focus to developing apps for Android and iOS and maintains a close partnership with Samsung for mobile Office apps.
