I see a lot of good info here, but it also comes down to the TV of course. My parents recently bought a new 4k HDR TV, but it was cheap. I talked them into bumping up one model, but that’s as far as they would go. They love it, but I can see that “color banding in gradients” issue you talked about, which my TV doesn’t have. I didn’t point it out to them though.

I won’t debate that the longer you keep it, the more you get your money’s worth, but a couple months ago, I did try to figure this out from a trade in perspective, so here you go…

A one year old Pro is worth $570 for trade in with Apple

A two year old Pro is worth $480 for trade in with Apple

A three year old Pro is worth $360 for trade in with Apple

With AT&T a one and two year old Pro (and 3 year old Max) trade in is worth $1000, and a 3 year old Pro trade in is worth $830
