My main problem is a dead laptop if the storage dies. (I still own a M1 Air anyway) Really wish I could run MacOS off of an external drive as a backup option but it is extremely picky(I've tried multiple drives, USB3.2 and TB3). Eventually being able to boot Asahi off of an external would be ideal, but if the SSD dies there will be no booting with how apple has done things. This is becoming a harder pill to swallow with how long I'm trying to keep machines. Which sucks because Apple has put out the only ARM chip worth a damn for daily driver computing. I even tried convincing myself to live off of a Microsoft Dev Kit just so I could have replaceable storage that doesn't brick the machine on death, but dear lord Qualcomm needs to put out some reliable drivers for windows, let alone linux.
