It does make a huge difference for readability of Chinese/Japanese/Korean in small sizes (e.g. comparable to reading a normal book or paper).

Now, that makes a good point, thank you!

Well, people have different opinions about it. I personally hate visible pixels with passion. I was an early adopter of HiDPI displays (starting with IBM T221 back in 2007), and I don't understand how anybody could settle for less after they see this gorgeous high resolution.

It's probably the fact that most people haven't experienced it. Regular consumers think macbooks have magically "better" displays than most windows laptops but can't name the exact reason. But just getting a high DPI laptop/monitor gets the same effect.
