Everyone I know over 70 would love something that works like a phone when folded but like a tablet unfolded -- big enough for text to be big, small enough to carry, and without fiddly interface -- and at a reasonable price for those anchored in 1980 prices.

(If those under 17 got attached to foldables, it would be an enduring franchise.)

For those of us in between, I'd love it if my foldable when unfolded were finally the OS of choice - iPadOS or iOS or even macOS. It would be the hub for hub-and-spoke devices...

It's an impossible ask, but perhaps....
