Word is that Linux based OSes are for tech savvy people. Truth is that if you need only web browser and sometimes office software Linux is best for your usecase. I've installed Manjaro (but any other one "easy" distro would work too) to my mothers laptop and she got used to it fast and barely notices difference between her laptop and her Windows machine on work. Seems to me like small thing you can do for your parents to keep them safer and more private on internet.

Yes, KDE is desktop enviroment installed in my moms case, GUI is very simmilar to Windows
@farhan
If you are there to install it, why not even ChromeOS. I don't know if it uses some sort of tracking telemetry, on Arch Linux and Manjaro its opt in.
@farhan There are laptop manufactures that pre install Linux if that's what you meant by "you don't have to install it". Afaik Dell ships some models with Ubuntu installed
@farhan In Serbia its little bit different, most laptops/pcs on market don't come with OS pre installed but people still install Windows anyway, pirated Windows for personal usage to be exact
@nikolal I can agree with you! I installed Ubuntu 20.04 on my step-fathers Laptop. I knew he wouldn't update his PC very often (if at all) I set a cronjob to do the job of updating once a week & set two aliases for youtube-dl in bash so he can download music/videos with a simple yt3 <link> // yt4 <link>.
I'm happy with 
, he's happy with *eh, thanks son, it just works* 
@nikolal This is definely true. Four years ago i installed lubuntu on the netbook of my father. He loved, don’t miss anything about Windows, and tell me that when he get enough money to buy another notebook, it’s has to be Linux. One goal for privacy

I switched my parent to Pop!_OS. It took just 2 weeks (1 week to let them test it and the other to ask some questions) and now they use it without thinking of it.
And my dad do woodworking, he barely use a computer (only e-mail and Web to manage his customer).
But the best part is there's full Windows theme to make it even easier to switch.
