Fully replace it or just switch to another one due to low battery? I haven't replaced any battery yet as I've had them for just a bit longer than 6 months, but I've had a couple cases of switching batteries to make sure I don't run out of battery unexpectedly, for example during a quizz night
I would be fine for the rest of my life with 0,005% (10 million €)
Now that I think about it some more, I don't know anyone who could not live a great life with "just" 10 million. Over 80 years that's 125k/year!
I believe bazzite offers that feature if you want it. You either select it during download or installation
What's the name of the option?
Could you add a link to the project?
I read their documentation yesterday, and it strongly advised a complete reinstall. While they do have a tool that eases the process of storing your setup and then recovering it on top of a new install, it's still significantly more complicated than just 'sudo apt upgrade'.
You have to reinstall mxlinux every time a new debian version comes out. Not really "normie" IMHO.
Unlikely
This seems like a good place to start
