It looks as if there will be an iPhone announcement on September 10th this year. So far it seems all but certain that a fingerprint scanner will be built into the home-button of the next iPhone, at least the premium model. This has fostered a lot of talk about a convex home button, so designed to house a biometrics sensor. However, a convex home button seems wrong. It just doesn't seem to go with the aesthetic of the iPhone. Perhaps if it was flat, or just barely convex to the point where it is not discernible I could understand. Otherwise, I would think Jony Ive would not build in the equivalent of an obvious "outie" belly button into the iPhone for any reason. No offense to all the beautiful people with "outie" belly buttons.
