But, for a non IT person, installing Linux, using the typical GUI tools is not specially hard to do. Write an ISO to a USB stick. Boot the PC. Answer the installer questions like language etc. And if something doesn't work, try a different distro.
The problems come when people suggest users use unfamiliar UIs, such as the command line or fiddling with config files, where, if you don't know the exact magic words, it fails to work.
I agree with the OP.
But swap the term "newbie" for "casual user" or "non IT user", and more people would agree. Even the nerdiest IT Pro was a newbie whenever they use a distro for the first time.
Avoid the term "normie" too, as people have different ideas of what normal is. There are more non IT, power users who have a deep knowledge of their applications, than all Linux users put together.
So this discussion is all around a sloppy choice of terminology.
Yes. I'm happy with the performance of the Kdenlive video editor on my weedy laptop with no GPU, 8gb ram, running Kubuntu. I did 20+ hour long videos for a conference no problem.
Yes. Owning a car is a constant expense. For something that gets used a small percent of the day.
I rent if I ever need a car. The rent by-the-minute schemes near me include charging or fuel, insurance and everything for ~25ct/minute. Ideal for local trips with passengers. Otherwise I bike everywhere in Munich.
Maybe the guide is not intended for some beginners after all?
