It's one of the (if not the) most beautiful Linux distributions out there.In the end, I chose elementary.io
After about 6 hours of use and tests, I think it will run well for watching livestreams and YouTube.
- very simple for a beginner
- mimics macOS user interface - which is something they are used to
- easy to install and update apps
- Firefox was available - installed uBlock Origin and Emsisoft
Great new life for an old all-in-one pc.
