While I have no experience with System76 and the quality of your devices, I doubt you can make any claims about the number of incidents with confidence. I have owned many devices that have had various quality issues that didn’t rise to the level where I felt it was worth going through some warranty procedure that may or may not alleviate the issue after spending an unknown amount of time & money on it. I don’t like the idea that the manufacturers of those devices take the absence of a complaint as confirmation that the computer has lived a long life without any sort of incident, major or minor.
