When they first started coming out with touch screen laptops, I drew up a laptop with a smaller touch screen located on the base (above the keyboard), and emailed it to all the laptop manufacturer's.
I thought that would keep the fingerprints off the main screen.
I did later see a prototype...
I have no way of knowing, but I would think that bigger is better on a modular laptop.
I watched Linus' video (posted above). Those things look pretty amazing.
And Linus' reviews seem pretty spot on.
There's a company called Framework, that makes... "modular" laptops.
So if a part of the laptop breaks, you can just replace that part... easily.
I don't know if they're any good or not... but it might be worth a look-see.

Linus not only likes it.... he's invested in...
