I think he meant that as an example. In his thread on debian-x from 
December, he makes the point more generally, and more convincingly, by 
pointing out the general pointlessness of setting exact dpi, given (for 
instance) how people sit at different distances to their monitors, so that 
a 12 point font can be enough for one person, too little for another, etc. 
Linus has tossed around the idea of "angular" size on the LKML, to more 
accurately describe how big something on a screen appears to the viewer, in 
an attempt to deal with the same basic problem, namely, that matching dpi 
to reality is usually pointless and can even be quite counterproductive.

All this just underlines the fact that whether something on the screen 
matches its size in reality doesn't matter at all to most people (and 
doesn't matter for all but a few classes of specialized applications). For 
most of us, it's just "cool". If it really mattered most of the time, Mac 
OS/Windows would do things differently.
