It is not an assumption, the W3C calls as a reference the 96dpi figure:


If the pixel density of the output device is very different from that of a 
typical computer display, the user agent should rescale pixel values.

Which the smaller screens/user-agents (such as an iPhone) set with a higher px 
density do, and quite well too (imho). IOW, use px, ems, or % - they are all 
relative units.

It is recommended that the reference pixel be the visual angle of one pixel on 
a device with a pixel density of 96dpi and a distance from the reader of an 
arm's length.

Beating a dead horse though methinks, just couldn't resist one more crack at 
it though, lol...
