For those that already know. The iPhone is said the be "better" than the retina of our eyes with 329 ppi, but it has to be at least 18 inches from our eyes in order to be dense than our eyes. The enV Touch has a ppi of 200? 100? 250? It's 310. the enV touch can also be "considered" a retina display if its 19 inches from our eyes. Hm...does that mean all phones have retina displayed...answer is a yes/no , because it depends how far the screen is away from you. And for those that didn't know, apple is lying about the retina display. The most dense screen out in the market is the Nokia E6 with a ppi of 333.
