One of the biggest selling points of the iPhone is fairness. The iPhone 4 has two colors, two different capacities, and two carriers. Other than that, everything is the same. Everyone using an iPhone has the same experience, so there is no reason for jealousy. (Well, until Apple comes out with the next model.)
The Android platform, on the other hand, is different. New Android phones hit the market constantly. Every new phone contains an improvement on something: the camera, the screen, the battery, etc. Each improvement is an opportunity for phone envy.
At the end of the day, smart phones are meaningless. We don’t need them, but we like them. I happen to like iPhones, and I think maybe it’s because I’d rather eliminate a source of envy from my life than to have an extra megapixel in my camera.
I think maybe that’s why Apple products appeal to a certain type of person. It’s a way to step out of the rat race. By simplifying your choices, it’s easier to believe that you have made the right choice.
