I did a arm chair calculation and the money saved on not having a headphone jack at 0.10pence per peice, and found that they didn't spend 200,000 quid on headphone jacks. (I read that since iphones after 6 don't have it, so that's 28 models of phone, that's millions of phones, so I guessed 2million phones multiplied by 0.10 which gave me 200,000.)
