Kindle fires can be found on sale for under $200. Autosync app works great. Lots of good apps to read comics. No reason to mess with linux. Plus it is easy enough to install the Play Store.
Over the years I have tried most mainstream distros. I have never seen a reason to use anything other than Debian. Never had it break due to upgrading, I have never tried Nix, Alpine, Gentoo, or Slackware, not many other others I haven’t tried since I started using Linux in 2000.
