I find the noise to be intolerable on my Adder WS even at idle, but would agree that it's nowhere near the biggest problem. That would be software support. I have been using Linux laptops for ten years and the only one that has ever failed to reliably wake from sleep is my System76.
They're junk by every metric I know of. Expensive, too. They have nothing going for them.
I am right now using a Lenovo X1 that has that problem. Previous gen also had that problem. And the one before that. Waking up from sleep is apparently difficult.
Their build quality feels poor. Sometimes it's hard to tell when an issue is just a vicissitude of using Linux or their fault, but I would overall not recommend.
Build quality is exactly what System76 is improving on by creating their first in-house laptop. All of System76's laptops to date have been adapted from designs from ODMs such as Clevo. When System76 moved their desktops in-house with their Thelio product line, they were well-built and well-received. I'm optimistic about their new Virgo laptop after seeing what they did with their Thelio desktops.
I would be willing to give them a shot one again one day (there are so few purveyors of pre-installed Linux computers), though not for the ~$1k Thelio costs.
Right now, WSL is working great for me, but Windows seems to be getting increasingly aggressive with wanting one to use their search, etc.
