(My work laptop is one of the few ARM laptops: Thinkpad T14s with Quallcomm Snapdragon Elite)
Battery is good, hardware is really rock solid (though I dislike the new plastic for the keyboard).
Really can’t complain, it’s nearly as good as my Macbook.
It runs Windows 11 today, and everything I need runs fine (jetbrains, rustc, clang, msvc, terraform and of course python).
I’m a technical CTO with infrastructure background, most of my time is spent in spreadsheets these days unfortunately.
However if you do manage to boot things up, hardware with open-source drivers should just work, for example Jeff Geerling has couple of videos on youtube about running his RPi with external AMD graphics cards connected via PCIe, and it works.
edit: actually it looks like this era is coming to an end; Crouton was archived earlier this year. Probably it still works on older models: https://github.com/dnschneid/crouton
