Time.com: John Arlidge’s interview with Jonathan Ive:

When it comes to obsolescence, Ive himself concedes he is carrying the fifth version of a phone that was only invented in 2007, with, yes, a new charger. But, he says: “One of the things that is distinct about our products is that they get reused and passed on.” What do you do with your old iPhones? “Erm. Actually, they’re not mine. They’re the company’s.”

(Emphasis mine.)

Hard to believe that the designer of the iPhone still carries around a 4S. Come on Apple, give the guy a new one!
