And what about us, iphone users that love idea of foldables but cant/dont want to switch… all we can do is wait if apple ever (doubt it) will release one (and no, no flip like foldable, rather fold5/pixel fold one).
Apple first needs to overcome the basic structure of the iPhone itself. It's in the name phone!
That is the inherent problem in order to project your screen. When you want to use it as an ex as a pure smartphone, you have to use an apple t. V, that's a ridiculous idea. Let's go one farther. Hook up an apple keyboard and an apple mouse or an apple track pad. And you're still limited and what you can do. It's really appealing.
Apple needs to get put of the mindset of protecting products from overlapping or one rendering the other obsolete: their prices already protect each product segment and product version already.
If Apple was smart they'd realize:
The low end iPads could serve as a secondary screen to all macs as well as the iPhone for those at home or travelling - a MUCH cheaper option for every customer that isn't a desktop publishing or video editing professional.
Next theyd realize a budding student or artist that wants, purchased or receives the low end iPad actually wants that larger screen canvas as well as the Apple Pencil for drawing!
I wouldn't expect a foldable or rollable screen iPhone to support Apple Pencil of any iteration in the first place. I highly doubt the majority of their customers do anyway.
