Does apple need to increase the ppi Retina Display? I am starting to feel that the next iPhone needs a higher ppi. Yes retina display is clear but there are times I feel it could be better. On iOS where those circles are that show you your cellar signal if ones not full it doesn't look so good. Retina Display is 326 ppi but the Samsung Galaxy s4 has a ppi of 441. Do you think apple needs to increase the number of pixels per inch?
