Two words: reading maps. A high-PPI screen is heaven for using Google Maps. I always get so frustrated on my 1080p screen: even with the browser map in full screen mode, I can't seem to see "enough" of it when browsing random geographical locations and trying to get a sense of how the surrounding area looks. A 239 PPI screen allows displaying a character in an 8-pixel font (eg. "fixed" on Linux) in a 1x1mm area. You could have all the tiniest roads and cities labelled on the map, even if barely readable.
