I'm willing to pay double the cost of a MacBook Pro for anything that can run Linux, similar performance to M5, have a decent battery, good touchpad, be silent, have a good display, be light and portable.
It doesn't exist. MacBook's simply have the best hardware, but terrible software/philosophy of software.
So I'd say their moat is hardware in general. Performance, yes to an extent, but it's performance vs heat vs energy vs battery life and all their peripherals.
This is Zenbook A16 right now, with recent patches posted to Linux ARM mailing list that support it in full.
Ghastly was macOS on an Intel MacBook Air.
