Nice. Upgraded a Thinkpad, installed Linux Mint and gave it to my dad. I have not heard anything from him about it for a couple of months. Was reminded of it with your post.
So wrote him right now and asked how it was going, and he replied that he loved it and uses it every day.
And that he had not had any problems he could not solve on his own. He’s 70 and a windows only heavy user - until now 🙂
As you said. Compelety painless.
+1 Kodi. Been running it for ages on an old laptop with a infared remote with USB dongle. Kodi is set to autostart. Pretty hands off and can stream to it from local sources using Kore for android.
EDIT: Can stream from local AND online sources using Kore ex Newpipe (Youtube).
