If you use an OS that handles high DPI very well, and where 98% of all apps handle it just as well (including resolution scaling), it is an absolute joy to my eyes to be able to use 4K at the same effective resolution (so basically 1080p, but double the resolution, double the sharpness).
Every time I use a 'non-retina' type of display (like an old laptop I use for testing or my 19" 1080p monitor), it feels like I'm looking through some dirty glass because of the blotchy effect.
I tried 4K on one linux environment (and documented the experience[1]), and according to numerous responses, my situation was not unique: if you try 4K on any Linux environment, and don't enjoy everything being tiny, then it's not a fun time trying to get everything to behave like you can with Apple's built in resolution scaling options.
