He puts up some nice technical arguments, and I'm sure a 4k monitor is right for him, but really it comes down to what you're actually comfortable with. I stopped worrying about resolution the moment I got my first 19" (CRT) monitor. Resolution was high enough to fit as much text as I needed, and really that's all that ever mattered. I've used retina displays but I've never felt they make enough of a difference to matter. I've worked on 32" displays, and while they're nice, I've never felt like I'm missing real estate when I move back to a 1080p display. Font smoothing has never bothered me, but what DOES bother me is this trend towards lower contrast, and "flat UIs" that lack any differentiation between sections in the UI. Win95, while ugly by today's standards, was easy to read and follow. And the black-on-white text is something I miss dearly.
