>Oddly, Microsoft has 32 bit x86 apps running on ARM, but 64 bit x86 apps are broken. It has been argued on HN that the reason was x86_64 patents that will very soon expire. Once that happens, Windows-on-ARM is very likely to have x86_64 emulation as well. Besdies, 99% of Windows software is available as 32bit. The software sectors that don't will either never port old stuff (games) or will port anyway for Mac and have an easy Windows port as a result (e.g. Adobe). >This is why Apple can afford to go all-in on ARM while Microsoft has to tap-dance back and forth between the two platforms. Microsoft is mostly a software company, rather than an hardware one. It doesn't matter to them on what processor type you run so long as it's their software. I suspect the biggest reason for focusing on ARM isn't Mac, it's Azure.
