I would love to find the "genius" who thought that the FaceTime app should be able to make regular phone calls and that call histories for all calling apps should be blended together.

That just cost us $50 because my wife tapped the previous call from me in her FaceTime history while I was in the UK and the stupid thing made an international call over the mobile network instead of a FaceTime call. No warning. No clue that the call was not a FaceTime call. Just more of Cook's poor UX. Fire him.
