Better (or simply more) ARM processors, no matter who makes them, are a win. They tend to be far more power-efficient, and with performance-per-watt improving each generation, pushing for wider ARM adoption is a practical step toward lowering overall energy consumption.

How is running desktop Linux on these?

I run desktop linux via postmarketOS on a Lenovo Duet 5 (Snapdragon 7c). It isn't the most powerful device and the webcam doesn't work but other than that it works well and battery life is excellent

> the webcam doesn't work

But.. ..why? Of all things, I would have expected the webcam to not be cpu-related..

IIRC, it's because the ARM designs tend to use camera modules that come from smartphone-land.

Cameras used on x86-64 usually just work using that usb webcam standard driver (what is that called again? uvcvideo?). But these smartphone-land cameras don't adhere to that standard, they probably don't connect using USB. They are designed to be used with the SoC vendor's downstream fork of Android or whatever, using proprietary blobs.

A similar thing is happening in Intel land recently, where the cameras use ipu6 / ipu7 chips rather than dumping simple frames over USB. But this way we get a higher resolution / quality at least.
