Personally, I don't like the idea of a split x86/ARM Windows-world -- it means larger install files, more compatibility issues, and more headaches for developers. I have zero interest in supporting it as a developer until it's either mass adopted, or my compiler workflow just one day automatically starts creating ARM binaries.
Will I also some day be forced to use the Windows app store as well then? Because I am also definitely not going to be doing that-- not a chance. ( I also don't push apps to the macOS store ; direct download only )
There is also a stack of obsolete ARM systems here that are useless because support ran out after a few years; no more updates, no more apps, and so no more use. This also includes Chromebooks and mobile phones. ARM systems just don't seem to have the legacy support that x86 systems have, so when the manufacturer decides it's over, it's done. Not so with x86 so far, where I still have multiple Intel 4770K systems running Windows 10 without issue. Is this issue being addressed?
Oddly, even my 2012 Macbook mini was fine until the M1-chips came out, and then it also stopped getting updates; I kept that system upgraded with SSDs and RAM, and it worked well as a headless Mac server for a decade.
I get that ARM is arguably more power efficient than x86, and I suppose Microsoft wants to compete with the M1 chips, the Windows laptops I do buy are beasts with Nvidia GPUs. If I want something running ARM, I'll use a budget Chromebook that I can just throw away in a few years for something newer.
So yeah, zero appeal to me.
