>The iOS DPI controls are the simplest and most straightforward of any contemporary system But they're simple because it was a startling realization that the original design was shortsighted. The iOS platform has had a mere 3 screen attributes thus far, and each has been an essentially hard-coded hack specific for it. It is not a laudable goal. They certainly didn't spearhead density-independent layout (and are more accurately one of the last to the party). >and high DPI displays are impractical In the workstation world people generally essentially placed their display based upon its DPI. A large, lower DPI display was wall mounted or placed at a greater distance (but serving more people), while a higher DPI display came closer to the user. The iOS platform is not the best example of density-independent layout. It is one of the worst among the modern era.
