How can an iPhone screen be as large as a 42" flatscreen, or a 13" MacBook?

Picture of an iPhone, Macbook, and a 42" LCD with approx the same scene from Lost lined up so that they "appear" the same size. I'll let someone with more time figure out the pixel arc view resolution differences, but basically each screen can provide a similar viewing experience. The blurry iPhone screen? Evidence that this is not a photoshop fake as the camera is focused on the distant screen (some 4 meters away).
