Linux kernel 5.19 is out, first from an Arm64 laptop – Computer – News

I have a dark brown suspicion that this is because Microsoft markets its operating system as backwards-compatible. That’s basically eating whole eggs; under Windows 11 you can run software written for Windows 3.1 with minimal intervention. That makes business happy (depending on who you ask, sysadmins generally prefer not to run legacy stuff, but that’s another discussion).

If they port Windows to ARM, all that legacy software doesn’t automatically go with it. So far, emulation implementations have been so slow that it hasn’t yielded a workable ARM machine with Windows.

In short, to switch to ARM Microsoft has to give up a very big selling point (as far as I have experienced so far) and then it suddenly becomes interesting to look at alternatives. Because at that moment you can also choose:

– Apple that has included emulation extensions in the hardware for good (or at least workable) legacy software performance and is well on its way to having everything native
– Linux which you can compile from scratch for ARM, including the applications you want to run

If you can’t run the software you want to run without noticeable performance loss, why choose Microsoft?
