Is it a note-taking station? Is it a decoration only? Is it your regular journal? Is it a shopping list maker? Is it on display or tucked away?
I use mine to quickly write down ideas, so that I don’t get distracted by other things on a computer or have to wait for a computer to boot up. Other than that it’s a conversation piece and a decoration.
Edit, I forgot to include, I have a Royal like the one below. It was the cheapest one at the antique store, and it has worked perfectly for the 10+ years I’ve owned it.
I have a Rheinmetall one from around the 30s that only half-works. It spends most of its days in the attic and only gets brought out to show people once in a while. I used it as a prop for a short film once, so I guess that was my favorite use for it.
