I am about to assemble new desktop PC with Manjaro on it. It will be dedicated to Kid’s use. I have 6 and 7 year olds and both are able to read.
I obviously need a super easy to use Desktop. I think they will mostly spend time in the browser, but I will not restrict them much.
I myself use XFCE, but I think that Gnome might be simpler from this perspective.
I have not used Gnome lately, so I am not sure.
