I do like the idea of them, same size phone takes up half the space in a pocket etc. But my current phone (that I’ve had since 2017) still works mostly fine.
I do think they’ve missed a trick by going all in on the foldable plastic display rather than two bezelless screens that folded out to look like one screen. I’m not phone designer but I think it might be more durable to not have the actual screen bending.
