> Microsoft’s platform has never been weaker. For all the growth in phones, every professional worker on the planet is sitting in front of a PC.

Or a Mac, or a Chromebook, or an iPad. It's hard to talk about this as a monolith since there are pretty distinct groups — most of the people I know who get to choose their device are using Mac or Linux (which is admittedly an atypical crowd of developers, scientists, lawyers, architects, etc.) but there are a ton of people who have professional jobs where that's not the case (e.g. everyone I know who works in healthcare uses some kind of Windows device which is so locked down that it might as well be an iPad, and I know some people at government agencies who are favoring ChromeOS for security reasons since you can lock those devices down so hard).

I make that distinction because it doesn't help Microsoft very much strategically if the cashier at McDonald's is sitting in front of a Windows box because they're interacting with a single application and will use whatever their next employer has standardized on when, say, they go somewhere which uses Square. Someone who uses Office is a bit more but as an increasing percentage of people aren't doing anything which they couldn't do in a browser, that's not as strong as it used to be. None of that means that Microsoft is going away but I think it does leave them really wondering how to avoid falling behind the next trend like they did with mobile devices.
