i cannot install linux on my mothers pc, because all she needs is...
excel, and a browser.
and excel isn't on linux.
and sure, i could show her libreoffice calc - i use that without issue - but she's not interested in learning anything new these days
and sure, installing excel, specifically, isn't super easy on windows. But generally, installing a piece of software on windows, is easier than linux. There's often an installer package downloadable from the website - where as for linux you're often greeted with a terminal command.
Thats not "mom friendly", especially not for the stereotypical "mom" who doesn't know tech.
Phones have made it super easy to install software - and the app stores for mac and windows are good solutions for these non-tech savvy people. Only a few distros have an alternative, as far as i know
