Okay, so lets compare:
in October 2011:
the Iphone 4s(the newly released phone) outsold the Iphone 4 (the newly "mid-Tier" Phone) 12.85-to-1
In October 2012:
the Iphone 5 (the newly released phone) outsold the Iphone 4s (the newly "mid-Tier" Phone) 2.96-to-1
So Fast Forward to October-Novemebr 2013
The Iphone 5s (the newly released phone) outsold the Iphone 5c (the newly "mid-Tier" Phone) Between 2-to-1 and 3-to-1
So, it appears that the Iphone 5c is doing on-par, if not better than would be expected for Apple's "mid-tier" phone.
Also, you may note that usually the Mid-Tier phone "picks up steam" over the following months after the new phone is relased. with the Iphone 4s, at it's peak, accounting for about 30% of new Iphone sales. But not until December.

I've seen reports that put the profit margin on the Iphone 5c about 10%-12% higher than estimates for the Iphone 5 (at this price point) So Apple could sell 10%-12% less of Iphone 5C than they
would have of Iphone 5 and still make more money.
Also, it gets even MORE complicated than this.
The profit on the Iphone 5S is about 36% higher than that of the Iphone 5 (at this price point). So this 12% less Iphones 5c that Apple sells (compared to the hypothetical Iphone 5 sales at this price point), ltes say that 40% of those went on to buy the 5s. Apple would be
UP 2% in profit.
So not only is the Iphone 5C selling
okay its selling at a higher profit margin than the 5 would have at this same price point. And, in the end perhaps the new design
cost Apple some sales, but did it cost them any
money?
