I disagree completely. Backwards compatibility has precisely nothing to do with why Windows is terrible nowadays.

And that's also entirely orthogonal to hardware - the hardware battle between ARM Mac and ARM PC is really a battle between Apple and Qualcomm (Apple won).

In hindsight, rather than relying on Snapdragon, Microsoft should have started designing their own high-efficiency ARM SoCs 15 years ago like Apple did. But I mean, everything is clear in hindsight isn't it.
