Your grandma doesn't need to know what wayland is to use linux. This is an enthusiast forum for people interested in this exact topic.

This isn't Linux, it's Arch running Hyprland. If Grandma wants that combination she knows what Wayland is.

If you want Linux that works, get a Chromebook. If you want to play games, use Bazzite.

ChromeOS is a far better "Grandma" distribution than Windows or MacOS. Linux is simultaneously both the most Grandma friendly and least Grandma friendly, including every point in between.

You need to compare apples to apples, aka pre-installed vendor supported operating systems. If you're comparing installing an unsupported OS on unsupported hardware, Linux is far superior. Try installing MacOS on a Windows computer or Windows on a Mac if you're truly masochistic.

Are you saying windows and macos do not have any bugs? I have news for you.

Also wevare talking here about archlinux + hyperland compositor, not the typical Fedora, Mint or Ubunti/Zorin distro. Tinkerer's gonna tinker while the other users just use their computer regardless of the OS.

Linux isn't a single OS. It's hundreds of different and weird combinations.

There are Linux distributions that are better than Windows or iOS for grandma to use as well as distributions where you need to be an expert to do anything.
