I work in Windows (company provided laptop) so on average I spend less time on my Linux PC. And I completely agree with you.
KDE as been my go-to desktop because of the familiarity. Some people argue that it has too much costumisation but the defaults give you everything to run a modern PC. While still allowing you to venture into the “terminal”.
My partner is a long time gamer on Windows. Her Win11 laptop doesn’t have the same performance as mine so I setup a gaming account for both. I barely told her anything on how to “operate” it and after a couple of times she has no problem on her own.
Just now, I came back to the pc and see kwrite open with a message from her. Never told her how to do that. She just searched for “notepad” on the menu like she would on Windows.
