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.
My mum owns an old Olivetti that seems to be a collectors item nowadays. Our mutual favourite (and only) use for it is to notify each other when we stumble across one for sale and how much it goes for. They seem to be in the area of €80-150 so not quite the family heirloom.
Edit; Oh wow. Haven’t checked prices for few years. Seems they are selling tenfold now.
