I think price will be a major factor in the fold adoption, and the rumors suggest it will be far outside the reach of what I'm willing to pay for a phone. (And being Apple, I'm sure those rumor have merit.) I'm sure it would be cool, but like the Vision Pro, I don't see the mass appeal. But I say this as someone who's considering downgrading to the base iphone 17 because of price and smaller form factor, so I'm not really the target the way I once was.
