I can't imagine the supply chain challenges inherent to startup laptop manufacturers. I think it's "go with what you have access to at reasonable prices, or forget about it. "
I don’t believe they actually make the hardware. I know sytem76 always just rebadges Clevo hardware. You were basically paying for Linux to be preinstalled and for the Linux focused support.
EDIT. Actually it looks like I was wrong about that. They do apparently at least make their own chassis’s unsure about the motherboard’s or screens though.
I think Framework is a good example of how smaller laptop OEMs end up shipping late, often on the order of three quarters. This is something else entirely, if any of these configurations are recent arrivals (I don't think they are).
