They call that resolution independence.  The whole thing behind  
Leopard and Vista was measurement by inches or centimeters instead of  
the futile pixel which has itself deeply embedded into everything.   
That's not to say that all applications therein won't use pixels or  
that either system is a panacea, but it's important to know what  
customers want and not just listen to your engineer's pipe dreams as  
seems to be the norm at Sun.  Personally I find this is the reason the  
"viability" of X11 in general is a problem for most regular users who  
expect consistency and modern practices.
