Many iPhone users seem to personally be on a 2 year cycle. Depreciation circa $300 / year.
Many others seem to be on a 3 year cycle, about as far as one can go before starting to really notice their handset lagging to the point of being unacceptable to them. Depreciation $200/year.
5c: Year old tech, in what for many will be "less pretigious" packaging, for $100 off the price of new tech in "more prestigious" packaging. You're immediately "out" $100, or $200, depending upon whether you are on the 3 year or the 2 year cycle.
$100/$600, for a savings of 17%. For 17% off, you're taking year old tech in a less prestigious package.
