Big phones fit in my pockets and in my wife's purse, but not in my kid's pockets. He chose the SE, because it fit his pockets. He's still growing, so we'll probably be able to postpone getting him a new phone until he's bigger, but it seems an odd choice for Apple to eliminate the most kid-friendly size. I would think that bringing more kids into the controlled theme park that is iOS would matter more than the margins on this particular device, but I guess Apple moves in mysterious ways.
