I'm looking forward to Snapdragon X, there's definitely occasions where it feels like I could use some more local perfomance.
One of the irritating things is that there's no native Chrome release for Windows-on-ARM. MS suggests that we use Edge but I'm quite comfortable with Chrome. So I use Chromium instead and it's great except it seems to be missing some DRM magic or something and therefore anything like gif files or webp and most videos on most websites can't be played back. However youtube does seem to be clever enough to see the browser's limitations and transcode/filter the content to something acceptable to Chromium. If I want to see those videos I switch to Edge.
It's good, it's fast, but it's not cheap.
But Apple doesn't ask HP or Dell to make its laptops. And Apple uses their own SoCs exclusively. So I don't think it would change anything other than some mild effect -- helping a larger shift in the developer ecosystem to make more developers accustomed to developing on ARM.
their x86 laptops are fast enough
they probably get as much battery life as they practically need
ARM cpus likely won't change the price much
Microsoft and everyone else has to support x86 until doomsday no matter what
so why should a consumer pick one?
Of course that is self-purchased laptops by young people; it doesn't really apply to cases where a school buys them.
Microsoft had a PPC port of NT, and it never was a commercial offering for Powerbooks. Despite the fact that it could work, you couldn't get it out-of-the-box. And Microsoft obviously had x86 support and Windows-on-x86 macbooks was never a supported configuration by Microsoft nor Apple.
They did on x86; Windows runs fine on Apple hardware with Boot Camp with support from both Apple and Microsoft. Why would ARM be any different?
Microsoft is of cause selling Windows for any system, they don't care what it is running on (ignoring the deal with Qualcomm for ARM). Apple also explicitly tells you how to install Windows on MacBooks [2] (the intel ones, not the newer ones, as Microsoft hasn't released a ARM Windows edition so far).
Until recently everything you say wouldn't be feasible was working exactly as I described and I don't see why we can't go back to that state when the exclusive deal for Qualcomm ends.
