I am using it daily... Its kinda hard to use tbh... except till you fixed it.

First, disable the Lid Opening in the BIOS. The keyboard case sucks for this task, making it constantly wake up when the lid is closed, as its easily missing the Magnet spot while transporting.

(Dont worry, it still can go to sleep when closing the lid when diabling the BIOS setting, but now you need to press the button for 2-3 seconds to wake up, thats one fix to make it usable)

The Keyboard will be pressed when you close the lid. Meaning that it will constantly wake up when you transport it as everything presses against the tablet, triggering some keys. So you need to create a systemd service that disables the keyboard close before suspend.target.. yes, the keyboard wakeup will re-enable itself for some reason, so its better to have a service triggering it everytime you go to suspend.

Suspending is slow af, its a bug with the SD-Card reader, so you need to disable that too on boot. I just put it in the same systemd service.

Don't buy the original Pen if you want to write. It has latency and sucks with the feeling. Buy a Penoval Pen or any other Pen. They will have USb-C charging and way less latency. The Tablet is using MPP I think as tech but I think some newer things also work.

Buy a good 12.9 inch Apple Paperlike or any other Matt screen protector. Havent tried this one yet but I will try it in a few days. (i accidentally bought an universal Matt Screen protector which was like 10% Matt from Brotec, while the same Brotec Matt protector for my tiny chromebook was like 100% Matt and felt like real paper. Matt is not always matt. I guess the Companies adjust their Levels to the use case of the device...)

Oh... btw. I used Arch Linux and a Forum talked about the issue, that all kernels are giving a kernel Panic at some point except linux-rt. This corrupted my system files after 2 Months of usage, when I awas using Godot... only the Linux-rt kernel was working perfectly they said in the forum. So don't use Arch Linux. Use anything else. I couldn't start X11 anymore and reinstalling all corrupt packages didn"t help. I started to use NixOs and kinda hate it, but I want to learn it for fun. It works but use smth like Kubuntu or Linux Mint. Idk.

Rotation doesn't work yet on Linux... afaik. Maybe it does but I can't manage to fix that.

After fullfilling all these Criteria, I am very very happy with this device. It was hard at the beginning and very stressfull, but now I start to love it somehow.

If someone wants me, to create a Repo with all my fixes and suggestions. Buy me a coffee and I do it. I don't have much time as a student. But you could do it yourself with researching, so why should I waste my time.
