96 DPI is one of several ideal settings in which the text appears perfectly adjusted. This is a matter of mathmatical configuration of the pixels/per/character...Imagine coloring in the individual squares on graph paper to create letters.
The benifit to having a higher resolution screen is that when letters in the 96 (or other "mathmatically ideally configured size") have "jagged" edges on diagonal slopes of the characters on lower resolution screens, a higher DPI setting can be found for the higher resolution screen that will yield the same physical size characters, but there will be many more pixels on each diagonal slope on the characters, and so they will appear less "jagged".
It begins to get difficult at todays "high" resolutions to see these clear differences because of the matte finishes of screens, which tend to cause a visual "bleeding" of light in an effort to give a softening effect.
...of course I could be just completely fulla shit.
PS, I propose the next big step in screen clarity will be the use of hexagonal shaped pixels instead of square.
