Among the changes found in the Mac OS X Lion preview is a new discovery of very high resolution technology that would be first in a mainstream desktop OS. Referred to as "HiDPI display modes," they would mimic the fourfold increase in resolution from scaling an iPhone app on an iPad but adjust every interface element to have the same relative size. The method spotted by MacRumors would greatly increase the detail but in a much more elegant way than before, where it had to use only vector scaling or multiple bitmaps and often couldn't scale at all.
