I've recently come back to studying German, after having taken a small break for a few months for a new job.

My main form of study is immersion (I recently stumbled across the books of Walter Moers and haven't looked back since) and conversation practice on iTalki.

Nowadays, I try my hardest to only buy tech second-hand and preferably as future proof and modular as possible. My go-to machines are a fully modded Lenovo Thinkpad T430, and a more humble Thinkpad X230, both running Linux (Ubuntu and PopOS respectively). They work just fine for my basic needs (mostly surfing, some occasional streaming and word processing). But they struggle during my conversation lessons on iTalki or Zoom, most of the time either overheating or freezing/stumbling. I realize this might be a Linux problem, but I have also found the web camera and built-in microphone on both machines to be really inadequate for video calls. I gave up using my own laptops for my language lessons over a year ago, and now have resorted to stealing my partners Macbook, which isn't ideal.

Do you have any recommendations for any more recent laptops that would offer a better video conference experience, while offering at least a removable battery? Pricewise it would be great to be find something below €500 used.

Okay -- I am looking for a decent but dirt cheap tablet, manly for recipes, spotify, youtube/VLC, maybe some simple puzzle games. I want the largest tablet I can get for the fewest dollars spent

Not a lot. I was looking at the Lenovo Tab M11 or something around there.

Also, ideally something that can take a crap-free Android ROM.

quick edit: I gave up on this for a few days because I got into the 'this one is better... but this one is better...' and before I knew it I was hitting a grand for something I'll barely use. I just ordered a Lenovo P11. I don't expect it to be amazing, but it'll be fine for the very basic tasks I'll be using it for.

Its surprising how much old stuff is for sale on Amazon. iPads from 2018, for instance. Doesn't seem right.

double edit: I returned the under-powered P11 and got a Lenovo Tab K11 LTE w/ 8gb and 128gb eMMC. Not a big fan of eMMC, but it'll be fine for my uses.
