I'll give John Ternus credit: the demos are interesting and fun . Maybe not $2k fun + inherent risk with buying the first generation of an Apple product particularly after the Apple Vision Pro, but still.
Samsung has already worked out the major kinks for folding displays, over dozens of products used by multiple phone manufacturers including themselves, and Android has worked out how to handle the various use cases between the outer screen and inner screen, when closed, open, or partially open, so Apple can pull from the current state of the art and launch with a more fully developed product, as they usually did before the Apple Vision Pro.
