Everything you require is not in the least beginner user problems. I'm talking basic issues faced by a person who only views emails, looks at spreadsheets and word documents and opens their browser
I get that, and my setup is definitely not beginner-friendly. But I think we need to agree on what beginners actually do, because I wouldn't say customising power settings falls into that category.
The problem as I see it is that even people who really are beginners sometimes want to reach for more advanced functionality, and different systems expose different advanced functions in a user-friendly way.
