It could not be simpler.
My grandfather in law kept getting scammed and installing viruses while on Windows. I installed Linux Mint on his desktop last year, setup automatic updates, created a non admin account for him, changed a few easy configurations to hide the technical stuff that appears when you turn the computer on, and he fucking loves it.
Keep in mind getting this man to login to Netflix on his TV is a minimum 30 minute long phone call. One time, we had to send people to check on him because his phone was off for 3 days straight; he put it on airplane mode and couldn’t figure out how to turn it off.
He has had 0, yes, exactly 0, problems with his computer since I installed Linux Mint. It’s faster, to point where he noticed and commented on it, and he finds it easier to use than Windows, which has been on every computer he has ever owned.
He brags to anyone who will give him the time of day how much he loves it.
I promise you, it’s really that easy.
As someone working in the Microsoft ecosystem at an MSP, we seriously wonder what the fuck goes on over there. We’re supposed to defend everything y’all do which is getting really hard to justify without sounding like idiots.
