>The only real use-case for crypto was doing crime.
It was never any good at that, either. Cryptocurrency is somewhat hard to censor but easy to track. And in practice, people go through centralized exchanges because blockchains work so badly.
I can second this. My Adder WS had atrocious build quality. The rubber feet fell off almost immediately. The charging port broke completely after a few months of normal use, was replaced under warranty, and then completely broke again. The fans constantly screamed even at idle, the case was floppy and creaky, the space bar cracked in half, and small bits of plastic repeatedly broke off.
Worse yet was the software. It would sometimes hang at random and never reliably woke from sleep. I've been using Linux laptops for ten years from a variety of manufacturers, most of which didn't officially support it, and my System76 had by far the worst compatibility.
