The iPhone Duo is the riskiest Apple product in years. It’s a huge rethink of what an iPhone is and could be, and it contains the seeds of many fascinating ideas that might be great in the future. But that future is yet to come. The iPhone Duo is also one of Apple’s messiest first-generation products in a long time, and right now it will delight gadget nerds and early adopters and likely frustrate everyone else.

The big phone news, though, was about a device that is kind of not a phone: the iPhone Duo, a $2,000 foldable device that Apple describes as like a “passport.” When closed, it looks like a slightly widened 5.4-inch iPhone; when opened, it expands into a 7.6-inch miniature tablet. Like numerous Android folding devices before it, it relies on a mechanical hinge and a flexible display with a seam (ideally, not prone to failure) in the middle.
