Even using the sale prices, an iMac is still cheaper than a Mini with the Kuycon.
My absolute favorite feature of Apple displays is that I don't need to have the brightness cranked to max all the time, even when sitting next to a window. Some of them are, dare I say it, too bright for a normal office at maximum brightness (yet still dim for comfort in a pitch black room).
There are some good alternatives if your budget stretches to $1000, though: Samsung's 27" ViewFinity S9 comes to mind, with 2880p and 600 nits.
Apple's solution to reflections is to overpower them. I use my MacBook in some bright public spaces and reflections have never been an issue. For an iMac which is more likely than a laptop to be used in an environment with controlled lighting, it's just a non-issue.
Looks to me like it would be the opposite unless a majority of your users are on a Mac. MacOS has a 30% market share in the USA and only around 15% globally.
That literally cannot be true, unless you're saying that your users are ALSO going to have a 218ppi desktop. If you're developing for phones, sorry, a 218ppi display is woefully inadequate for replicating what the phone looks like because phones (modern iPhones) have 450+ ppi, more than TWICE the ppi of the display you're using.
An apple display is nice. But it's absolutely NOT absolutely required for anything no matter the creative work you're doing, because there's nothing it matches except developing stuff for display on that exact display.
I have bought a 32" 4k monitor like five years ago and have really regretted it. Sure fonts are slightly crisper but I would rather have preferred to have a higher refresh rate. Newer games will barely run on 4k if you don't have top of the like hardware or will need frame generation trickery. Plus the odd app that still doesn't support hidpi displays properly.
I feel like 1440p is already the sweet spot.
