As a preface: This post is not to knock anyone who went out and bought either variant of 24" iMac. This is merely an observation.
With the Intel 21.5" 4K Retina iMacs, the amount of power and performance that you'd get would always be greater than that of the contemporary Mac mini, MacBook Air, and whichever 13" MacBook Pro was out at the time (let alone the 2-port Intel variants). It would have a higher starting price tag, but you'd always get substantially more computing and graphics horsepower out of it.
Now, with the M1 being mostly the same across all four Mac models that have it in terms of performance. The M1 iMac, when spec'ed similarly to the previous most expensive M1 Mac (the 2-port 13" MacBook Pro), is $200 more.
I'm not sure, in the history of Macs, let alone personal computing, that we've had a scenario where you have a laptop and a desktop with the exact same specs and, roughly, the exact same performance where the desktop was actually MORE money than the laptop. If anything, the desktop is usually cheaper, assuming that kind of equivalency. This is true of the Mac mini in relation to the MacBook Air and the 2-port 13" MacBook Pro. But the iMac seems to change this a bit.
