I admit to being confused about the cries for a 27" iMac. Count me as one of the many people who was mad Apple didn’t make a great stand alone display anymore and needed a solid pro desktop that doesn’t cost $5000. The 27" iMacs were a bad compromise– an expensive display with an end of life connected to a computer that slowly creeped upwards in power due to the lack of any other options.
The world we live in now, with a Mac mini and Mac Studio that cover significantly more range, affordably, as great computers and the very solid (if pricy) Studio Display is far better for the typical professional user. And the 24" iMac is a great consumer computer.
Everything about the current Mac desktop lineup (and displays) is more coherent and better than it’s been in at least a decade, if not more.
