They seem to want those who would’ve bought a high spec iMac (or briefly, an iMac Pro) to instead buy a midrange-or-above Mini or a Studio instead. With the M-series, the iMac returned to its roots as the “family computer” or “grandma email box” kind of machine.
It’s too bad. A high end iMac still holds a lot of appeal, especially for those seeking clean desk setups. I’m using an MBP hooked up to dual monitors through a dock right now and it’s fine, but I do miss how clean my desk was back when it was a VESA mounted iMac Pro and companion monitor.
I was just thinking the same thing. The M-series is so good, the demand for uber-desktops is smaller than ever. And all professionals I know truly want/need the portability of a laptop.
And receptionists! Don't forget receptionists. :)
