My partner tried popos and it was awful. Iirc, it didn’t even seem to support her multiple monitors? I can’t remember for sure, but we had some issues and bailed pretty quickly. She and I both are now rocking Kubuntu, which, as you mentioned, was a much easier transition from Windows for her (and me), though I’d have her try bazzite today if Kubuntu wasn’t already set up.
I really wish he’d changed the title to something like “Bootleg DVDs Are Cheapened In a Weird Way” or something to make it more obvious that this was the case. I had no idea that this was what had happened (though I had wondered while watching the video) until I saw a thread about the video.
