I would love to see Cupertino once again embrace the one-and-done precept (and the core of their ethos) behind their AIO iMac lineup by offering port-parity between the Mini and their 24" iMac...take it home, put it on the desk, turn it on, and be done. Keep the Mini for folks for whom "upgrading their processor needs more frequently" is a must, or for those who would like to opt for a monitor/display of their choice.
While they're at it, churn their under-performing-in-sales Studio Displays into a reimagined 27" iMac with Pro and Max M4 chips and port-parity with the Studio desktop for we one-and-done folks and keep the Studio for those whose needs mirror the Mini users (above).
Finally, grab some of the current production run of 28", 32", 42" HDR panels and (finally, at long last) serve up an HDR iMac with Pro, Max and Ultra M4 chips for we ≥5-year ROI users and keep Studio and Mac Pro for the more, er, particular and selective users.
Steve spent over a decade fostering a solid user base of loyal and enthusiastic iMac users that the post-Steve Mac desktop team has decided to squander...how does a CEO allow that to happen? No doubt there's been an incessant clamor from the ≥27" iMac user base for a new M-series lineup, so, um, what's the hold-up, Tim?
All-in-one is what Apple is.
