The incomplete history of Duo devices

Apple announced its first folding-screen device, the iPhone Duo, but the name and form factor are not new. The Verge notes that Samsung, Google, and earlier products called Duo all got there first, while Apple is emphasizing a custom nano-texture display meant to reduce crease visibility.

The launch highlights Apple’s familiar strategy of entering a maturing category late and trying to redefine expectations through polish, branding, and ecosystem integration. If the crease-reduction technology is convincing, Apple could help push foldables further into the mainstream despite not being first.
