The rationale for embiggening the iPhone (screen size and ergonomics) doesn't apply to headsets. That's missing the point. My comment wasn't about rationales, it was about the difficulty of miniaturization. The fact that the iPhone got larger -- and that consumers demanded a larger phone -- took all the pressure off the miniaturization program. That will not be the case for the VP.
