Apple's first foldable, the iPhone Duo, is a deliberate departure from the incremental updates that have defined the iPhone for years. The Verge's review describes it as the riskiest Apple product in years, with a passport-like shape and a 1.4:1 aspect ratio on both displays. That design choice is a bet that landscape-oriented, tablet-like use will win over the tall-and-narrow format that other foldables have used.
Both the full review and a separate piece by Allison Johnson agree on the standout feature: the nano-texture matte inner display. It hides the crease, cuts glare, and makes reading feel more comfortable. Johnson says she hopes every other foldable maker copies it. The review notes the crease is mostly invisible but can be felt and seen in certain lighting.
Where the sources differ is emphasis. The full review spends more time on trade-offs: the cover display is small, the device is heavy and bulky, it gets hot, and the cameras are just OK. Johnson acknowledges the Duo has "all the messiness of a first-gen product" but focuses on the matte screen as the reason she keeps using it. For a $1,999 device, that split verdict suggests Apple has a compelling idea that isn't fully baked yet.
