Is the iPhone Duo worth it over a regular iPhone?

It depends on whether you want a foldable. The Duo gives you a large inner screen that folds away, which a standard iPhone cannot match. In return you accept more weight, a hinge and a first-generation design.

How does it compare with Samsung's foldables?

Samsung's Galaxy Z Fold line has had several generations to refine its hinge and crease. The Duo counters with Apple's chip, software support and ecosystem integration. Neither is clearly better; it comes down to which ecosystem you live in.

What storage should I pick?

The Duo comes in 256GB, 512GB and 1TB. Photos, video and games fill space quickly on a large screen, so heavy media users should lean toward the larger tiers.

Does it come with a charger?

Apple has shipped recent iPhones without a power adapter in the box. Expect the phone and a charging cable in the original retail packaging, and plan to use your own USB-C charger.

Is the folding screen durable?

Foldable screens are softer than glass and more sensitive to grit and sharp objects. Treat the inner display carefully and keep it away from keys and coins.
