It's all about the android. As some have mentioned you can do more with it, as in there is more freedom to customize. It just feels like the phone for those who enjoy choice as opposed to the iPhone which is a cult following.
Also, apple may have made a strategic misstep removing the headphone jack as that may go over with the millenials, but may have put off many of their users 40+ of age who believe wired always sounds better.
