It is incredible the corner Apple has on the smartphone market, retail market, online presence. I think the failing retail stores in the age of online shopping is impressive.
The iPhone and the rest of Apple's product line are not idiot proof as many people have made the reference of, myself included. However, for the Millennials that have grown up with technology from the start, it is fairly simple. Automatic WiFi back ups when the phone charges and simple tools like iTunes to backup phones make it easy to maintain a device. Android offers no such service at the length that Apple does.
So while people are generally still ignorant, Apple is doing a great job at making some things that would normally be an issue for most people really simple.
Samsung, LG, Motorola, HTC and the rest of the bunch do not support their devices nearly as well. Samsung has made efforts with Kies, but most people have issues with Kies.
If any other OEMs can pick up the pace on the support side, this could change. Poor Samsung just hasn't found a way to repeatedly entice customers year after year as Apple has.
