I'm curious as to thoughts people have regarding the long-term (i.e., lifetime) costs of ownership for the iPhone 5S versus 5C, especially in light of the current sale prices. By lifetime, I mean taking into account the net upfront cost and then subtracting the resale valuesay, a few weeks after models would launch in the fall of 2015. Specifically, imagine a 8-10% tax rate, which would put the cost of an iPhone 5C at WalMart around $49, and put the cost of an iPhone 5S at WalMart around $206, for a net upfront difference around $157. Using Gazelle's prices as a benchmark, a 16GB iPhone 4S fetches $165, while a 16GB iPhone 4 fetches $100. (Prior to launch, I recall the iPhone 4S value was $200; I'm not sure what the corresponding iPhone 4 price was.) However, private sale values obviously would be higher for either model. Those numbers all suggest to me that the iPhone 5C has the lower long-term cost of ownership (extrapolating, saving $157 upfront but only giving up $65 plus some incremental amount on resale). However, given that it is a new design that apparently has lower demand, I'm not sure if the comparisons to the iPhone 4S and iPhone 4 go out the window. I'd be curious to hear what others think on the matter.
