I think it is dead, as well, especially if Apple releases a ~$2000 Apple Studio Display Pro with MiniLED and ProMotion at WWDC as Ross Young predicts will happen.
So if you want/need to replace an iMac 5K, you have three choices:
- "Good" - Mac mini (M1 or M2) with Apple Studio Display
- "Better" - Mac Studio M1 Max with Apple Studio Display
- "Best" - Mac Studio M1 Ultra with Apple Studio Display Pro
Yes, they all cost more than the $1800 PoS iMac 5K configuration, but that's how Apple rolls now. Deal with it or move on, I guess. *shrug*
