I want a folding iPhone that is essentially the Huawei Mate X (6.6" screen folded, 8" unfolded). Perhaps one that folds in the opposite direction like the Galaxy Fold. I'm confident Apple can eventually figure out the best way to approach this. But I really would love such a device and I hope Apple offers one in the next 2 to 3 years. I think there would be a big market for it.
