1) I am surprised there is no mention of trading it back to apple? 2) I am sure putting a decent “churn” schedule for apple devices is already been done right? Top of my head I can imagine coming up with one where for of the major product line apple offers (mbp, iPad, iPhone) we can look at the typical depreciation curve and find optimal “get in” points and “get out” points right? How hard could it be. I agreed there is a friction and activation energy needed to going down to the Apple Store and trading it in but you could get a new device every 1-2 years and keep largely churning the same out of money plus a slightly more to top up (call it premium to avoid the anger /pain inflicted by not doing it.)
What am I missing here ?
