You are partially right and partially wrong.
Sure, the iMac Pro as it is now is really a crap value and I really don't see the reason for its existence anymore. Either you get beefed up iMac or you go Mac Pro. Whoever says otherwise is either having very specific need or is just inflexible.
However, on the other hand, Apple can make the iMac Pro good value if they actually put the XDR screen in (maybe with some sacrifices) as that could justify being inbetween but I feel that is crazy thinking right here.
Honest, I think Apple should kill the iMac Pro (or rethink it), make the entry level Mac Pro better value and just have that. Redesign on the normal iMac with better thermals to allow for better specs etc. and call it a day. I don't know, i feel the product line is messy right now
Makes sense to me.
