Ugh. Tell me you don't actually believe that?
The resolution of the iPhone 4 was predetermined to simply pixel-double existing iPhone applications (no sloppy scaling or black-bordered apps for the legacy stockpile). It is only marginally denser than several Android phones, and is a big ball of WGAF wrapped in ridiculous market speak.
It's great that they increased the resolution to be more competitive with most other high end smartphones, but the retina stuff is such a stretch of nonsense.
