I have been using Android phones since 2010. The first was HTC Desire, the flagman of Anrdoid devices then. Then Samsung Galaxy Nexus.
Recently I have decided to try switching to iPhone. In part because of terrible behavior of my Android phone: slowness, battery draining. In part because iOS has more and better apps. You know that developers mostly target iOS platform first, not only because iOS users are more willing to pay for apps, but also because development for Android is much more expensive and painful: http://techcrunch.com/2014/04/06/the-fallacy-of-android-first/
