Same to you too. You are overthinking this.
Apple did the something they have done for the last few years. Release a new iPhone, drop the old phones price by $100.... except there is one slight difference. The lower end model now has a plastic shell. The question is why?
The answer is quite simple. The metal-shell of the iPhone is "relatively" expensive to make. Furthermore it requires very expensive and sophisticated machinery. Now every year Apple sells more and more iPhones. If all the iPhones Apple sold this year were metal-shelled iPhone 5/5s style it would require more machinery to make. By changing the 5 into a plastic shell able is able to reallocate all that manufacturing capacity to a single line (i.e. the 5s). Better yet since the plastic is cheaper to make Apple's profit margins on last year design increase too.
That's the whole reason of the 5c. To transfer manufacturing capacity to the 5s without needing invest so heavily in infrastructure as well as increasing the profit margin on the lower-end device.
What's wrong with you? I was responding and agreeing with the guy for saying Apple makes a higher margin with the 5C. Then you tell me I'm overthinking, that they are doing it for the higher margin. If you're saying the same thing as the guy I'm agreeing with, then I'm agreeing with you (at least on the profit margin part ).
Do.you.not.see.that?
Also, I'm not overthinking anything. I do this for a living, understanding how brand strategy works. If anything were all oversimplifying because this is macrumors, not Harvard Business Review.
iPhone 5S is a halo product to a 5C. They can use the halo product to control the brand image, while also dip into more customer intimate product lines that by traditional nature sell in high volumes because the price is lower. Taking last years model and offering multiple colors is a play into the need to express personality and satisfy preference (customer intimacy).
People don't buy Beats headphones, for example, to hear audiophile music. They buy it because on top of it playing good/decent sound quality it's primarily a social proof and means of personality expression. Although there's obviously a range there in which a person will make that buying decision.
There is a gap with the iPhone 5 in that it only came in black or white. Sure it expressed mastery and luxury, but not personality. (Like a green Kia Soul expresses more personality than a white BMW, usually personality expression is less expensive, and mastery is more expensive but less about personality expression and more about purpose and importance.)
To conclude this: I agree with you, and more so the original poster I was responding to before you became so confused. But on top of that, know that Apple isn't just playing a "operational efficiency" game, they are playing a psychological one in which a percentage of the population will always value options and personality expression above mastery. So Apple can dip into that customer segment as well.
We'll see how this slight venture plays out.
