The Iphone is a lot more than a device that is used for phone calls or for surfing around the internet. There are a number of reasons why apple users tend to stick to it. Firstly, Iphones tend to have very nicely built hardware. Apart from that, their software rarely ever glitches along with its hardware.
Furthermore, their cloud services happen to be among the best of all. In the end, the support that apple provides is exceptionally good. Also, there are no negative attack ads from apple. Instead, they only focus on their own game and target the right people to sell their products to.
