I am surprised you are looking at Monterey this early in its lifespan, but I agree that a 27" iMac with M1 Max or M1 Pro silicon would be an awesome machine but unless you are into serious Audio or Video production work do you really need that kind of power and expense? A current model 24" iMac with an M1 processor and a second matching sized HDMI Monitor would probably save you money and once you try dual monitors you will never want to go back to a single screen. (Or at least that is my experience).

In any case the 27" iMac with Apple silicon should be available early next year assuming there are no further supply chain glitches.

If we knew what it was we were doing, it wouldn't be called research, would it?
