Yeah, I was actually thinking of SystemReady when I wrote my comment, and I have some vague understanding that Microsoft is all-in on it because ex. even their phones used UEFI, which is kind of beautiful. So the pieces are there, but sadly not nearly-universal like with x86 PCs:\ Separately, I will grant that drivers are their own sticking point, but I would like for them to be approximately the only sticking point. And even on x86 drivers are a problem; Linux generally has good mainline coverage of most networking cards, even wifi is good these days, but fingerprint readers have always been hit-or-miss. I just wish we could get to the point where once the drivers are upstreamed everything does Just Work and we can be free of "well this distro has a Raspberry Pi image but if you want to try an Orange Pi you need to find an OS that supports that exact board..."
