Here’s the thing. The iPhone 5C has nothing to do with price.
It’s just that instead of putting the year-old iPhone 5 in slot #2, they’ve created the 5C to debut in that slot. The 5C is, effectively, an iPhone 5. Same A6, same camera, same just about everything — except for the most obvious difference, its array of colorful plastic shells. … The prices of the iPhone tiers remain the same as last year. What changes with the 5C is that the middle tier is suddenly more appealing, and has a brand of its own that Apple can promote apart from the flagship 5S.
In marketing, what looks new is new.
This move is about establishing the iPhone as a two-sibling family, like how the MacBooks have both the Airs and the Pros. Think of the 5C as the Air, and the 5S as the Pro. Or iMac and Mac Pro. The iPhone is growing up as a product family.
