The fact that it works with the pencil is a huge selling point for me. I wasn't really interested in a folding iPhone, but having something I can write on without also needing to carry an extra device or pocket notebook is really cool.
My interest in a folding iPhone depends on the form-factor of the most compact aspect ratio. Apple seems really reluctant to show the folded phone versus other models. I can see the appeal of the tranformation into a larger form factor, but I already have issues with the size of Apple phones. And I have big hands. My hands cramp on small handhelds like the Switch. But I'd also like to be able to single hand respond to things on my phone if it's possible.
Yeah, I currently have a Samsung Galaxy Note 10+, Book 3 Pro 360, and a Kindle Scribe Colorsoft as well as a Wacom One attached to a MacBook and more styluses scattered around my house and bags than I could easily count, but this makes me at least a little curious about switching away from Wacom EMR.
