My brother is 12 and just like other people of his age he can’t use a computer properly because he is only familiar with mobile devices and dumbed-down computers
I recently dual-booted Fedora KDE and Windows 10 on his laptop. Showed him Discovery and told him, “This is the app store. Everything you’ll ever need is here, and if you can’t find something just tell me and I’ll add it there”. I also set up bottles telling him “Your non-steam games are here”. He installed Steam and other apps himself
I guess he is a better Linux user than Linus Sebastian since he installed Steam without breaking his OS…
The tech support questions and stuff like “Can you install this for me?” or “Is this a virus?” dropped to zero. He only asks me things like “What was the name of PowerPoint for Linux” once in a while
After a week I have hardly ever seen my brother use Windows. He says Fedora is “like iOS” and he absolutely loved it
I use Arch and he keeps telling me “Why are you doing that nerdy terminal stuff just use Fedora”. He also keeps explaining to me why Fedora better than my “nerd OS”
I have used Linux for a while and transitioned the wife and kids to Linux Mint a couple years ago.
They know it is different than Windows but never miss anything as the alternatives are as good or better. The kids are used to mobile and tablets so know of app store and so on. The only downside is getting some games their friends play working, like Roblox. But for the most part alternatives like Minetest are fine (better).
The upside is IMHO massive in terms of privacy, security, user friendless and sysadm stuff.
It just works and we’re happy with it!
