We will eventually see "foldable MacBook" because I genuinely want a 20" screen in my backpack or even just a smaller 16" MacBook. I guess not coming before 2035
It makes me think of a Bento-box laptop with a foldable keyboard and a tri-fold display, where both the display and the keyboard unfold when you open the computer. Extremely thick, but a very small footprint when closed.
I'm not sure whether that's amazing or something that'll bankrupt any company that tries to sell it with longer than a 3-day warranty.
