Amazon’s Graviton2 (originally from Annapurna Labs) is apparently delivering significant efficiency on the server side. Laptops will be there soon enough even without windows.

We've seen some of this already, for example with Microsoft's SQ1/SQ2 SoC manufactured with Qualcomm for the Surface Pro X series of laptops. They already emulate x86 well enough to run apps compiled for 32bit x86, and they should be coming out with 64bit support soon.

Once Microsoft is shipping these layers within Windows, it's only a matter of time before the use of ARM CPUs in more laptops takes off.

Does windows on ARM support emulation of x86 apps? Probably the biggest advantage for windows right now is tat you can run apps from 20 years ago perfectly fine, and of course the large library of playable games built over the years.
