Why Linux is Great
My desktop (Mint 21, Xfce) while I am thinking about #10
1. It needs fewer resources than Windows and OSX
It runs just fine on older hardware
2. No viruses
3. You can customize it
Very easy with Xfce, KDE or Cinnamon
4. It has a DIY charm
You can adapt things to your liking
5. It is free
As in free of charge and also not owned by a company
6. Great diversity of desktop environments and software
Though this can also be a disadvantage, as it is confusing for new users
7. Great community
There is a culture of learning and helping others
8. Using it gives you a feeling of achievement
At least, if you are an Arch user ;-)
9. Some distributions are very easy to use
I'm using Mint. Everybody can use Mint.
10. It is very stable
Never had any issues with Mint, Debian or Ubuntu.
11. It increases the lifespan of old chromebooks
12. It is great for amateur programmers
Python 3 is preinstalled. You can do a lot with C or Rust.
