Nah, you could’ve waited 5 years to port if you were concerned about your x86 binaries not being supported, the bigger deal was that Apple was shipping good ARM computers and if you’re a developer, you don’t want your app to seem slow on what consumers can see is clearly a fast machine.

Microsoft has made multiple abortive lethargic gestures towards ARM, but has yet to get people excited about an ARM computer that runs Windows.

Part of the trick was that ARM previously held a "cheaper, more efficient, smaller than x86" slot, and in the Windows ecosystem that was competing for the bottom of the market. Apple's ability to launch the M1 completely demolished that position and made an ARM chip the positively better choice, and it's just not something that Microsoft could ever have tried. MS have always treated the actual hardware as first and foremost someone else's problem. Which is a shame, because when they do produce their own kit, it tends to be very good.

CoPilot+ PC could have been it, but then they completly messed up with Recall, naturally no one wants to have such thing on their computers if they can avoid it.
