> durability (dust, water)

Not just dust and water but folding screens are plastic with a mohs hardness of 2-3, as opposed to normal phones with glass screens which are a 6-7 hardness. I like having phones that can't be permanently damaged by pressing my fingernail a little hard into it.

I also can trivially replace the screen on my regular phone at home, whereas I'd have to get a folding phone professionally repaired for many hundreds of dollars.
