I think ARM based Windows OS is going to be another MS orphan product, where low volumes will mean support will be poor and long term development is not assured.
The lesson is don't buy new products from MS unless you know it's going to be successful (Catch 22).
I dunno that I agree with that line of thought anymore. Yeah Windows RT (32bit ARM version of Windows 8) had a lot of limitations, and ultimately didn't work out well. However Windows 10 on ARM has been a huge improvement over RT, and now Windows 11 is a significant improvement over 10, so it seems to me they've made consistent progress for the ARM platform. Sure there are still things that don't work, but that list has gotten smaller over the last few years. But I guess time will tell.
Again, I don't consider this issue a problem with ARM itself since it used to work fine.
