IBM standard cards are one 48th of a barleycorn thick. I believe IBM measured from the 1932 Iowa Reference Barleycorn, now kept in the vault inside Mt Rushmore.

Those are both serious blockers for me tbh, I like to take it out away from home and watch YT / Nebula vids. I’m keeping am eye on Asahi’s progress though.

I have an M1 Macbook Air (under half price secondhand thanks to a superficial dent on a corner) and while I agree I love having such powerful hardware that sips battery so sparingly, MacOS can go eat a whole bag of stale dicks. Homebrew makes it… tolerable, but I’m holding out hope for that new Qualcomm ARM laptop - the recent benchmarks beat Apple’s chips handily.
