It's a question of bottleneck analysis. For those with exquisite
(20/10) visual acuity, the bottleneck on legibility is the ability of
the system to faithfully produce the characters at tiny sizes, without
pixellation or other degradation. Such a person can benefit from very
high resolution even on small devices.

For those with blurry visual accuity (20/50), the bottleneck is
their own vision, so that characters must be large for the person to
deduce their outlines. To such a person, resolution is moot: Any
reasonable resolution will be better than their eyesight. What such a
person needs is *big*.
