well the iPhone 4 has 614,400 pixels over a 3.5 in screen...

You can never have too many DPI lol 

There must be a point of negligible return where cramming more pixels only increase development cost and not improve it graphical wise.

which according to apple the iPhone's "retina display" is at that point given the average viewing distance. Can't wait to get a 30 in monitor with that DPI lol.
