I have the iPhone 5c and my upgrade is in sept 16'
I had the iPhone 6S prior to this 6S Plus. I moved to the plus for 2 reasons. One is that I traded my iPad for an Apple Watch and the Plus is a nice tweener device. Two is that we have new baby (was pregnant at the time) and the OIS would be better for capturing moving kids from what I've read.
Congratulations on your new addition to the family, sir...
6S. I upgrade every year bc I'm addicted to mobile gadgets.
My favorite phone ever
