jp makes a valid point.
Just going to throw out some rough numbers (in the U.S.) assuming $50 for your data plan, for 3 years.
3 year iphoneSE experience ($400 + 36 months * $50) = $2200
3 year cheap Android experience ($250 + 36 months * $50) = $2050
Now compare the camera, frame rate, screen quality, security, stability, and support of an iphone 5 vs a $250 Android. When looking at the 3 year cost, you are paying a 10% premium for a far superior experience.
