Right, but most icons do not exist in a high resolution format yet (as far as I know, I would appreciate if somebody to correct me on this, if I am wrong). Apple's retina display works because they have graphics that are the same physical size on screen. When I switch from my MacBook Pro display to an external Samsung display, the icon and text both get smaller.
