Have one sat on the desk next to me right now.
Booted off a Fedora 31 USB stick with kernel 5.3.7.
Seems to work great -- wifi, bluetooth (it's an Intel device), suspend/resume, cameras even work. Tested the SDHC card slot and all good. Keyboard shortcuts work as expected (can't dock it/undock yet as the live USB is plugged into the keyboard).
Pen works although it seems to register before it touches the screen and I can't get the buttons to do anything. No big deal for me though.
Downsides -- no automatic screen rotation and the rotation is off during boot, also defaults to 200% scaling and some of the icons don't respect 100% when you set it (might be Wayland though, I will run with X.org once I have it fully installed).
Certainly, the out of the box Linux compatibility is better than I've had with any tablet so far and I'm happy. It's a nice little machine. And I'm sure some of those niggles I can fix or will get fixed (this Fedora USB stick is not the latest).
Seems sturdy enough, quite a nice feel to it overall, and the tablet sits nice and firm on the keyboard. How reliable it turns out to be only time will tell but for now I'm impressed -- for the money it's superb.
