I don't mean to speak against Windows on ARM viability - it's a necessary product and it's well executed. But Windows on ARM is still building a market, and can't run significant high performance software yet.

Even for gaming it can't run anything released in the last 15 years in the current Snapdragons, which by itself excludes a really big portion of Bootcamp use cases.

Part of them. If you just want to use one-off old software then emulation is adequate. If you actually care about performance, then no, not really.
