Either I don't understand the used apple market.. or I agree this is crazy. Someone spends $25k on new hardware, waits a year, and expects to sell it for $23k? Unless the ram issues save him, and cost of new goes up, I don't see how that was going to work.
Apple products have had relatively high resale for a while. Only losing 8% in a year is probably extra unusual, and 1-year-old wasn't really ever the sweet spot, but a "sell used privately after a few years, roll onto the new one" has been a relatively common play.
Doing this particular one is definitely expecting the market squeeze to continue. "Worst case" is back to more "normal" depreciation. Where I'd expect to only be able to recoup more like 18k. But... if you look at GPU prices the last 3 years... it's not a crazy assumption that it won't drop that fast.
iPhone example since those are easiest to find in quantity: new iPhone 16 Pro Max for $1200, Gazelle would want $866 for "execllent" condition. Lost ~28% for one-model-back. iPhone 15 Pro Max, though: excellent priced at $667 here, only down another 23%, and gives you basically half-priced-upgrade if you can sell it for that and roll into the newest.
So to have never-more-than-one-model-old rough estimate at today's value-holding you'd be out $3600 for three new phones, with getting 1732 of that back, or 1868 for it (with a $334-per-year incremental cost of upgrade).
For never-more-than-two-models-back you'd be out $2400, getting back $866, for net $1534 spend, with a $167 incremental per-year upgrade cost once you buy the first one. Pretty good if you keep the phone in excellent condition and are happy to budget a bit over $10/month to be on a every-two-year upgrade train.
Well, you'd also eat the tax...

You could almost sell a RTX 3090 for more today than what it cost brand new when it came out six years ago
This is the case in lots of markets, e.g. look at used cars, luxury goods and more. Some of it is driven by inflation/the rapid devaluation of the dollar. General and AI-adjacent compute in particular hasn't come down in price in a long while.
A lot of expensive things hold their value well. I have a friend who is really into telescopes and he now owns a $100,000 telescope but he didn't directly buy such an expensive scope. He started out with much cheaper ones and was able to sell them for about what he bought them for to help fund more expensive ones over 20 years. It is really interesting.
Well, Apple is literally not offering the M3 512GB studios currently. You can’t even back order one.
They are selling on EBay for over $20k, used.
