I am hoping there will be a large screen iMac Pro in the future - the all-in-one form factor of iMac is incredible and I'm part of the customer base who does not want a Mac Studio or Mac mini with a separate display, and the current iMac is too small and lacks the power for heavy pro workflows.
Apple has basically committed itself to the 220 dpi 'retina' display practice that entails using lower volume panels (since few other vendors use 5K 27", for example), and such displays are expensive. Coupled with Apple's pricing (often described in unflattering terms), a display at 32" built-in display would need to be 6K and both it and the AIO system would cost beyond what mainstream consumers are willing to pay.
If there was a demand for such an iMac, Apple would sell it. Unfortunately, there is none and they will not produce it.
There may well be a demand for traditional 27" consumer-targeted iMacs, but seemingly not an iMac Apple is willing to sell at a price that would work.
So basically a Mac Studio built into a 5K Retina display. Would throw my $$$$ at that straight away.
And when that system came to its useful end-of-life, you'd toss out a 5K retina 27" display (just as I'm looking at doing with the iMac I'm on now, if FedEx ever gets my ordered M4 Pro MacMini here to replace it) instead of having that display for 2 or 3 computer systems.
I think the right approach for Apple is to make a monitor with a Mac mini mounting point, users then able to combine the two into a neat all in one. Maybe incorporate a power connector in the mechanism such that you only need the one cable and power button.
This makes strong sense. Better yet, create a parallel line of modified Mac Minis that are designed as modules to fit in a slot on the back of a new Apple Studio Display. So you buy an (expensive!) ASD, but you get 27", 5K', lauded spatial audio, a (hopefully improved) webcam with Center Stage, excellent color accuracy out of the box, good brightness and default to glossy, and you can use that for 2 or 3 Mac systems before it dies or you toss it.
I would replace the iMac Pro with a new one if released, but I have little interest in a Mac mini or studio with separate monitor.
What does the all-in-one offer that's so compelling to you that you accept making the built-in high quality but expensive display disposable in that it's only useable for that one Mac system? When you upgrade, time to toss it.
How likely are the people interested in the higher end (and priced) power systems with 'Pro' in the name to keep using the same system for 8+ years? Does making the display disposable make sense for them?
There's a key dynamic in the iMac approach directly contrary to the logic in another thread I'm following about the M4 Mac Mini. People ask should I get a basic spec. M4 (or mildly up spec.'d, like 24 gig RAM and 512 gig SSD) over an M4 Pro (with or without higher RAM and/or SSD), or should I 'future proof' it by buying the M4 Pro chip and/or more RAM and SSD?
In other words, should I buy cheaper and upgrade every 4 years, or pay 2 or 3 times the money and upgrade ever 8 years, or some variation?
The majority view seems to be that, given Apple's allegedly egregious pricing on RAM and SSD upgrades, it makes sense to buy closer to the base model and upgrade twice as often.
With the iMac (at least without target display mode), you throw away a high quality display ever time you upgrade. So borrowing the logic from the Mac Mini thread, you either need to toss your (built-in) display twice as often (if not more), or else up-spec. ('future proof') the iMac to it's expected to remain a solid choice for 7 or 8 years.
Maybe that's less problematic for iMacs with a 24" display, but when you're talking 27 (or 32!) inch retina displays, that's a game changer.
Plus if Apple delivers our hypothetical 27 or 32" iMac with spatial audio, you also throw away a high quality in-monitor speaker system. And likely a webcam with Center Stage.
This is not my 1st iMac, and I get the minimalistic elegance, but the only logical way forward I see is a user-swappable 'Mac Mini module' so the computing guts can be upgraded. Seems that would be the best of all worlds.
Look at what the ASD costs; is a 27" iMac model still viable today? How could a 32" inch be?
