As far as screen resolution goes, I find that there are two usage scenarios that people generally fall into, either:
a. Only like to have what they immediately need visible, so they are not distracted.
b. Like to have plenty of screen space to be able to go quickly to whatever they need to quickly.
Needless to say, the latter are doomed to an expensive monitor setup!
Laptop users will be used to having to swap windows while they work, whereas PC box users tend to want pixels, and lots of them.
I have always wanted plenty of pixels, even up to four 30" 2560x1600 monitors at once, but now have a more modest 55" 4K TV and two Dell 23.5" FHD touchscreens.
When we did our CD a decade ago, one of our musicians was looking around for a new DAW after Apple abandoned PC users of Logic. When he saw one of my earlier multi-monitor setups, he concluded that Cubase was too complex for him, but then he was used to using an 800x600 monitor for his DAW. To me, that would be like trying to watch TV through a keyhole!
