if that’s all you need it to do: browser, kitra, libreoffice and not much else… any mainstream distribution will work.
fedora’s ‘atomic’ distributions tick your boxes. minimal terminal exposure, hard to break, and infrequent demands of user password.
silverblue (gnome) or kinoite (kde). kde is a traditional desktop experience, but gnome would be excellent for your rather basic set-up.






i have my boss’s old one here that’s pretty much only used for testing mobile web and for its camera. i use a ‘dumb’ phone, and its camera doesn’t work (was crap-tier anyway when it did). i think it has 10 on it. it doesn’t leave the office, doesn’t get used that much, and has no google account linked to it anymore since it was totally reset when it was replaced earlier in the year… the inability to use google play to install a few apps reduces its usefulness. i got f-droid on it but not everything is available from it.
