The “pro imac” always seemed like a waste to me. The computer always becomes obsolete before the monitor. Much better to seperate them for “pros”.
Except it depends what you mean by "obsolete" - I can think of a lot of uses for a second hand iMac Pro at a sensible price, and even my 2017 high-end regular iMac is still a pretty capable bit of kit, even if it's a long way from bleeding edge... but it's no use without a display.
Anyway, I kinda agree about the iMac Pro in that people who needed that much power would also be likely to need specialist display setups and enough peripherals to make the all-in-one bit moot - and sometimes that means things like colour calibrated/certified 1440p displays rather than the absolute best resolution. It's the $2000-$2500 5k iMac models that leave the hole.
My new one is 5K2K UltraWide… basically my dying iMacs 27” screen times 2, side by side, with no break or bezel down the middle. I’m doubting Apple will get around to an ultra-wide themselves for many years.
That's ultrawide - 5120x2160, 21:9 - so it has the same vertical resolution and pixel density as a 4k UHD (3840x2160) display of the same height, and will pose the same issues with probably needing "scaled mode" to get the system font/icon/menus etc. a sensible size. It's not
equivalent to a "5k" 5120x2880 (in a world where 3840 is '4k' I guess that's 5k3k?) display which is the optimum for MacOS for a 27" 16:9 display.
Don't get me wrong - "scaled mode" may have been an issue with Intel UHD Graphics but a M1/Pro/Max should eat that for breakfast, and 4k
is retina at desktop viewing distances, so you've proven the point that there is a wonderful world of alternative displays out there, but there
is a MacOS-related advantage to using 27", 5k 16:9 displays - and there are approximately zero of those on the market (if the LG has been discontinued).
What Apple could have done to fill that gap would have been to release an M1 Pro Mac Studio starting at $1499. Looking at the MBP's the price difference between the base M1 Pro and base M1 Max is $500.
here is no option between the $700 Mac Mini and $2000 Mac Studio, I don't count the 16GB Mac mini as that different. Even though it is price point where a lot of people would be interested in something.
You can't just dismiss the 8GB RAM and 256GB SSD in the lowest end Mini, especially when the RAM is now non-upgradeable and part and parcel of deciding which SoC you need. 512GB SSD is probably compulsory if you want to install bulky Pro software like Logic
and have enough space for your work-in-progress video/audio projects on the fast drive. If you
don't want that then the 8GB/256GB is probably fine.
So I don't think it's valid to dismiss the $1099 Mini config as an intermediate between the base Mini and the Studio.
Now, looking at MBP 14" prices, the difference between the M1 Max and the M1 Pro is $600 (the RAM upgrade from 16 to 32GB is part of the chip) - so working
back from the M1 Max Studio that would put a hypothetical 16GB/512 M1 Pro Studio at $1400. (Yeah, that reasoning isn't cast iron
but it's the best you can do with the available info).
So, yeah, that sounds like a reasonable intermediate option between M1 Mini and Studio.
However, remember, the Max supports one more external display than the Pro - and I don't think anybody knows what's happening with TB4 ports and PCIe or if the Pro could support all the ports on the M1 Max Studio (I thought the only Pro/Max difference was GPU cores, but the Max-only Studio has rather more I/O than on the M1 Pro & Max MBPs).
I think there's another way of looking at it, though: The M1 Pro is basically an M1 Max with half the GPU cores chopped off, resulting in a GPU that is more powerful than anything else in a thin & light laptop (with decent battery life) but
isn't anything special compared to desktop PC GPUs (or even bulky gaming/portable workstation class laptops).
If price is not your #1 priority (and you're getting a Mac, so it isn't)
and you're buying a desktop, so heat & battery life isn't your #1 priority, either, then how much do you need to "save" by getting what is, by Apple standards, a mobile-class GPU?
