The big future that I see for foldables is as tablets for note takers.

Microsoft and Apple have already proven that students are willing to shell out the money to buy $1000+ products just to take hand written digital notes on. If Samsung or someone else could create a foldable that's in the ~$1500 range that can fold out into the size of an ipad mini AND has a good pen usage and storage situation, I believe it will sell incredibly well.

It'd be so cool to be able to walk to a lecture with only your phone.

I used to take notes on my Newton MessagePad back at a time when college professors would _not_ allow folks to use laptops for notetaking --- agree, in addition to folding, you pretty much need a stylus for note-taking (and for an Apple Pencil, I'd worry about the "tick" one gets each time it's touched to the screen).

That said, these days I use a Samsung Galaxy Note 10+, Amazon Kindle Scribe w/ Premium Pen, Samsung Galaxy Book 3 Pro 360, and when at a desk, a MacBook and Wacom One display, all with Wacom EMR --- no folding devices, since there doesn't yet seem to be one which uses the normal frequencies (most recent foldables used the same frequency for the stylus as is usually used for the eraser?!?).

I'd give a lot for a competitor to the Lenovo Yoga Book 9i which used a Wacom EMR stylus, or for a phone which used a standard Wacom EMR stylus.

I’d be tempted by a foldable iPhone if (and only if) they have a stylus, but I don’t expect them to.

The form factor doesn’t lend itself to storing a comfortably sized “pencil” along with the phone, and god forbid an Apple accessory exist that doesn’t feel perfectly integrated with the product it goes with.
