It is completely relevant. Basically, you can now replace aging Windows PCs with VDI hosted on ARM clouds, and people won't know or be able to tell a difference. You will now have x86 Win32 apps, arm64 Win32 apps, and UWP running on what's just another SKU of Win10. And since every piece of software for Windows must support 32-bit x86, there is full backwards comaptibilty. You won't need to wait for some mission-critical bit of software to be ported, and in the Windows world, there is plenty of mission-critical abandonware, trust me. Now it gets the AOT/JIT treatment. Microsoft just made enterprise a reality for ARM64 servers by crossing the proverbial rubicon. Suddenly, if you use Windows and Microsoft products, you can still buy into ARM data centers and clouds.
