Based on evidence from reselling sites (eBay, Amazon etc.) we can observe a trend that iPhones on average depreciate far less and slower than for example Samsungs (or other phones that lose their value even faster). Now why is that?
Note that I am not talking about nominal prices (iPhones are on average more expensive than Samsungs) but the percentage change. I am also not asking as a "fanboy" - it is just an observation I made.
