> Part of the problem is that no one can (or wants to) force the issue. Apple got up on stage and said, "three years from now, we won't be selling Intel-based laptops. If you don't get on the train, you'll be left behind." Microsoft won't do that. Without that commitment, why should a software firm port its applications to ARM? Every software firm should be thinking, "if we don't do any work, Windows on ARM will be miserable and never get traction." Likewise, any chip maker is going to say, "I don't want to invest in ARM laptop/desktop chips until it's clear that ARM is going to be a major part of the Windows ecosystem." Finally customers are going to think, "I'm not going to buy an ARM laptop until it's clear that Microsoft, the chipmakers, and software firms are all behind this." No one is willing to commit to the future because that future won't exist unless they all move in unison.

Honestly how hard is it to port software to ARM?

Electron apps just work, .NET just works and Java does too. So does every language that isn't C/C++. And even on the C/C++ side, unless you are doing some funky things I doubt it's more effort than adding a release configuration that targets ARM in the build pipeline.
