target use case is a server for LLMs where memory bandwidth is very important iirc, not really a desktop for the consumer. this is probably a one off product that was pitched to them by amd
kde is very pretty and fun but there aren't really beginner focused kde distros, I myself started on kde neon but that's not really too polished and kubuntu is a bit meh
i had doubts about mint but i tried it out and it REALLY handholds you well imo
one thing kde does really well though is getting people interested in linux, because the customisation options are so exposed and user friendly
iirc prahou also posts on mastodon
