The 27" iMac that's comparable to the $2000 Mac Studio was the $2800 iMac, not the $1800 iMac. The Mac Studio at a minimum costs more than the $1800 iMac, so they're not even in the same ballpark. If Apple had included an M1 27" iMac, that would have been comparable, since that's essentially a 24" M1 iMac with a 3" bigger screen. An M1 Pro would have been comparable to the $2400 iMac while the M1 Max is basically the $2800 iMac. Put in the M1 Ultra, that is basically the discontinued iMac Pro at $4999, which funny enough is the cost of the upgraded M1 Ultra with 64 GPU cores (the non-binned version). Because they're in the ballpark, that's how you know the M1 Ultra is really Apple's replacement for the old iMac Pro, not the $2800 iMac.Huh? In the last decade, I have purchased two imac 27's. At msrp, combined they were still cheaper than a single studio combo. A nice side effect of that was I got a significant monitor upgrade each time (2013 qhd > 2017 5k/brighter).
If I buy a studio combo now, then upgrade just the mac in the future, I will have paid more than 3 imacs with no upgrade to the display.
My calcuations are based on the $2800 27" iMac, which would have been the base M1 Max. It's comparable to paying $2000 for the Mac itself and another $800 for the monitor (we got a bargain with the AIO on monitor costs, but on the flip side we get rid of it when we upgrade). Upgrade the iMac 27" once and you'd pay $5600 for both systems, but you'd have two monitors, one of which you'd sell, trade-in to Apple, or just junk it. Upgrading a Mac Studio in a couple years time would be paying $4000+1600 = $5600 total for old and new ($2000 for each Mac Studio and $1600 for the 27" Studio Display), compared to the $5600 for the two iMacs. Hey, exactly the same price. Now upgrade a second time, say four years down the line, and you'd pay about $7600 combined for the three systems (3 Mac Studios and 1 monitor). If you had bought three 27" iMacs, that would have been $8,200, a savings of $600. So yeah, in the long run, you save a bit of money, though you'd have to upgrade twice to do that.
