I believe what they are saying (hoping for?) is that since there are many Windows compatible laptops with touchscreens (unlike macbooks), Android app experience on them might be better.
I’m excited to see that Apple is unifying their hardware architectures across their various form factors of computing devices.
That’ll be interesting in the future.
So xbox, (phones?), tablets, laptops, desktops, servers ran the same Windows essentially with different shells.
Windows also supports multiple hardware architectures - we just need the external ecosystem to thrive as well. We see it in graphics with nvidia and amd but compute/cpu progress limped through most of 2012-2018?.
Windows for ARM is still in preview, I believe.
Surface Pro X running on ARM was released to public 2 years ago. We had x86onARM translation since 2018 I believe.
