I prefer to use products and services before inevitable enshittification, not after the curve. Refusing to use them won’t change their fate.

I have this one from aliexpress with touch and I use it with cheap surface-like tablet (Chuwi HI10 MAX) and sometimes with Windows 10 desktop or Samsung Dex. It works with one usb-c cable or with mini-hdmi and power cable, colour rendering is acceptable, view angles are great. Unfortunately, although touch works great on desktop I can't configure it to work on linux tablet. As far as I know, it's impossible(?) to have two proper touch screens with Wayland.
OpenSUSE Tumbleweed. Recently I bought cheap Surface-like x86 tablet on a rather recent hardware, and running Debian and its cousins required more tinkering than I was willing to do, so I decided to go with a more modern rolling release. Tried Arch for a few months, bricked it from mixing stable and testing branches, tried Fedora, and finally settled in Tumbleweed. I like it for being on the bleeding edge and exceptionally stable at the same time, perhaps thanks to robust OpenSUSE Build Service automated testing. And it is from a European company, that can't hurt.
