Apple recent strategy of bringing out an iphablet than includes all new best bits of the smaller new iphone has been strong one but this year the iphone 7 plus is a phone thats marketly better than the smaller moddel.
That mostly achived through two thing improved battry life and an inovative camera. The former is always going to be better given the larger size but by adding a duel camera setup the mix apple has mad concious effort to make the7 plus seem like a distincty different choice. Thats true price of phome very high but phone perfomance bettre than price.
