Hi, Mark. I agree the iMac's display will doubtless be fantastic and hard to match at that price. But given the choice between a 24in screen and, say, Dell’s 27in 4K UHD monitor, I'd take the extra screen space every time. And you could get two of them side by side, plus a Mac mini, for the price of the iMac. The Retina stuff is nice, but less critical on a screen you sit 3ft from than on a phone held inches from your face.
