I had a Windows Phone. Switched from an iPhone 4 or 4S to a white Lumia. Loved that thing so much, the camera was YEARS ahead of its time! It was shockingly shortsighted for Nadella to kill it, and I always thought that he was doing it just to put another in the coffin on the Ballmer years. But we all knew that Apple’s iOS and Google’s Android, Microsoft’s biggest rivals, would never let Windows get a foothold on their own platforms, so a long, expensive, painful buildout that was already several years underway was the only possible play in a world that would one day be not only mobile first, but virtually mobile only. We still are not in that world, but Microsoft is nowhere to be found in the mobile space. Satya is infinitely better than Ballmer, but this monumental own goal was incredibly damaging. Heck, Microsoft dumped $10B into OpenAI without batting an eye; they could have easily afforded to play the long game in mobile. But that would have had a lot of credit go to Ballmer, and Satya is not about that, in my opinion.
