I recently got the same tablet in a cheap second-hand deal. Seller had never used it so battery is excellent. Bought it because I wanted to kill time by installing Linux, and it actually wasn't as bad as expected. Could have just disabled secure boot and be done with it, but that was probably where I spent most of my time. Waydroid is was easy to install so I can run both Android and Gnome, but x86-64 Android is so limited in software that I uninstalled it.

What I found was that it's a cool way to play Heroes of Might and Magic 3. Playing that game on a tablet gives the feeling of playing an interactive board game. It runs smoothly in Wine. A pretty important thing in the game is the ability to right click, which didn't work, and I would assume Windows have the same problem (I don't think Windows tablet support would be sufficient), so I wrote a mouse hook in win32 c that enables long press to right click.

There's lots of annoying nuances, like the Gnome 42 icons in the activity list is really small, the on screen keyboard is small and almost unusable in landscape mode (but big in portrait mode) and camera works for gstreamer apps only so no browser support (and the suggested fix doesn't work for Fedora 36).

I removed Windows and have locked the boot order so it won't be altered.

All in all 10/10 as a tablet for someone looking for excuses to tinker with Linux (and win32!).
