I went from a note 2 to an iPhone 6+. I honestly don't get the iPhone hype. The iPhone UI drives me crazy. i miss having contact shortcuts on my home screen, I miss swiping to the the left to reply to a missed call with a text. I miss the swype keyboard. I miss having a dedicated back button. Basically, all of the actions I do the most, like calling or texting my wife is now 2-5 clicks more than what it was on the note. When iPhone users talk about the better Apple UI, I take it as code for looking and behaving like their previous phone.
Furthermore, I don't understand all the love for the App Store. I've explored it and haven't found an app there that I would want that wasn't also available on android, and usually the android versions were better because I could purchase digital content on the android version (kindle app and audible are great examples of this).
