Any business which might have made use of this to take advantage of things like ARM devices being cheaper/more available than x86 devices (you literally can’t find an x86 tablet worth using for less than $400) long since ported to Android. Microsoft sort of missed the boat with ARM. Every time I see those little android based terminals littered around small businesses I think “man this sure is a business Microsoft lost for no real reason”
I wish Microsoft would support the WoA use case people could actually take advantage of. Using windows in a Mac VM. That would be by far the most effective way to get people to develop for the platform, not this product.
Plus, if you read Microsoft documentation on Windows on ARM so far, Microsoft doesn't actually expect you to use an IDE on these machines - but rather run your code remotely on them. You'll be a lot happier with your IDE running on a more powerful machine. Of course, if you do that, the lack of a GPU on the M1 for a Windows on ARM VM becomes not really an issue.
When that happens it doesn't matter what CPU I have, things are nearly locked up.
I have little recent Windows development experience, but I wonder if Windows on native Arm gets the same sort of latency/lagginess reduction that going from Intel to Arm on macOS does? Even if the raw processing power is less, I would be happy with the tradeoff if Windows felt even snappier.
