I'm gonna be honest brother, right now there aren't any good ARM tablets running linux that aren't overpriced and niche products or laptops without a keyboard.

The closest you get for a tablet on a price is taking a look on what https://wiki.postmarketos.org/wiki/Devices has to offer, i've also seen some github pages about people running linux on Xiaomi MI Pads.

like this one. I can't garantee you're going to have a good experience running it this way, but you technically can.

I also encourage you to look for x86 tablets on aliexpress, some of them are decent and will run any linux distro you want.
