@f0x I've been using mine for a couple days. There are still a few hardware issues they need to work out. When the battery goes below 60%, your system will lock up if you have an NVME drive installed. Someone is working on designing a PCB to fix that.
There are also some rollover issues with the keyboard, you can't press control shift tab and some other combinations. There is also some buzzing from some components on the board if your brightness is below around 70%.
Mainline kernel support is getting better. Manjaro has the best hardware support right now, the GPU performance is a lot better than the stock OS, although suspend doesn't work. Swaywm is working pretty well on it.
