Otherwise, I think Federighi is the next best person to take Cook's place as CEO. The guy, I think, can certainly talk and engage the audience. One thing that caught my eye was that he was wearing a very expensive shirt on the day of the presentation unveiling last week and that was a bit distracting. He needs to dress a bit darker to people focus more on what he's saying and what's on the presentation screen. Dress "less loudly" in darker tones so the presentation stands out.
I really do question your age or at the very least, your maturity. The presentation speaks for itself. It doesn't matter what he is wearing. Just because Steve did it doesn't make it the right way.
