Windows 10 on ARM exists because Microsoft has already seen how slowly Intel moves to address real-world industry needs when it has monopoly control of the chipset industry. But Windows 10 on ARM is important---yes, even to those who don’t see the point of the platform---for many, many reasons. And anyone who cares at all about Windows or Microsoft should be rooting for its success.
That anyone needs to explain this---or to defend Windows 10 on ARM---here in early 2019 is a bit troubling. But based on some unexpected feedback to a tip about an early peek at the native version of Firefox for Windows 10 on ARM, it’s clear that some still don’t understand the need for this platform. And that others are even hostile towards it for some reason. (And in one weird case, hostile towards me too.)
