Depends on what you used to do with your PC. If you are used to writing power shell scripts for doing stuff on your PC, it might take a bit longer to adapt to Linux. If you mainly used GUIs to do small stuff it is much easier to adapt.
So in conclusion yes, as long as the non Power user has some technical knowledge and doesn’t get scared away, if the UI looks slightly different.
So non-experts have an easier time switching vs a Windows power user?
