As crazy as this may sound, and I'm probably alone in thinking this but iTunes is a big reason why I always end up back in iOS. The ease of syncing everything is made so easy via iTunes. I've tried 3rd party solutions on Android and it just never works out for me. People may hate iTunes but I for one love it and won't use any other software.
Another reason which is very important to me is the iPhone's music player UI. I'm long past carrying a separate music device with me and having a good music player on my phone is crucial for me. I've tried all the best Android music players, and while they are good and provide EQ settings, I find their UI and lousy 3rd party iTunes sync something to be desired. All iPhone needs is proper EQ customization, and I have a feeling that with Beats acquisition that will be coming in the future.
Simply put, iOS and iPhone just has what I need in a phone and that's all I really care about. Now just bring me a full HD 4.7"+ screen and I'll be set for life
