Apple is a dictatorship. Proprietary ways have assured they have a captive user base.
Conversely Android is a breath of fresh air. One is able to do as they wish, creating exactly the right smartphone functionality for their workflow. While the platform had the normal bugs, annoyances et al during its early years, now with the arrival of Android ver 4.x.x it's mature, fast, fun, and very reliable.
An experience that easily equals that of iOS.
Even the mere act of swiping through photos feels more natural on iOS than it does on Android.
Android gives you options and customizability, sure. iPhone gives you polish, and strives for transparency between the user and the content they're trying to reach. Two different flavors for different types of people.
