It depends 100% on what you do with your media stuff. I do a lot of design work so I like to have a large screen. Of course, less is always better in an RV but I need my computer and monitor, attachable keyboard, and tablet for the most ease of my work. Therefore I have no inclination to get rid of any of it.
I’m not sure what I would upgrade to unless you mean a better computer that doesn’t shut down randomly on me 😉 Ack! I guess I could get a super thin flat screen monitor but my current one works fine I don’t feel the need to change it.
Best of luck with your set up!
