Apple's hardware VP asks buyers to hold him accountable for the iPhone Duo crease

A folding phone gets judged in the first few seconds an owner tilts it under a ceiling light, hunting for the line across the middle. Marieb's answer is about that tilt. "When you look at glossy displays, their specularity makes it very easy to pick up topology differences," he said ^[5]. The matte finish, he said, is more forgiving of hinge changes over time ^[6].

That second point assumes the hinge changes. What Apple has put on the record is that the change will be harder to see, and that distinction matters to anyone taking up his invitation: "Hold us accountable to that, please" ^[4]. Holding Apple to it takes a measurement, and whoever runs the test first will define it. The excerpts published by MacRumors and 9to5Mac do not include a fold-cycle rating or a crease-depth figure ^[17].

The hinge claim is about feel. Feel is not a specification, and a buyer can only compare one unit against another on a shop counter. Apple worked the torque profile heavily, Marieb said, "to have it feel solid, like a high-end automobile's car door, when you shut it" ^[7], and he called that "design intent" ^[15]. He said "a lot of blood, sweat, and tears went into that" ^[8].

He is blunter about accessories. "Personally, when I see someone put a screen protector on their iPhone, it makes my skin crawl, because we work so hard to make beautiful front screens," he said ^[11].

Pre-orders open October 16 and the phone ships October 23 ^[12], seven days apart ^[16], from $1,999 ^[13]. The part of the claim that concerns extended use ^[3] will not be answerable for months after that. Anyone who commits on day one pays before that evidence exists.

Two things are worth keeping apart until then: whether the fold geometry changes with use, and whether the owner can see it when it does. Apple answered the second and conceded part of the first ^[6]. The experiment that matches that answer uses one lamp at a fixed angle and distance, with a photograph at unboxing and another after six months of daily folding. By Marieb's own account of specularity ^[5], the light source is the variable, so the setup has to be identical both times.
