Well, the iphone is excessively expensive really (also vs their manufacturing costs). The iphone 6(+) has a poor screen-to-body (65% for the iphone 6 which is a joke really) and the screen resolution is sub-standard.
Thus it is surely viable to consider alternatives. However, I will not argue that iphones are great.
