Why? An iPhone at ~0.5 meters from your eyes would take up around the same visual area as a full-size film projected all the way across the auditorium.
Film in combination with eyes creates an almost fractal viewing experience. You can look closely at portions of the screen and see greater detail. With an iphone, you get that meager resolution and that's it. I find myself pulling the thing ever closer until it may as well be a panorama but frustratingly, never seeing any more detail. The opposite actually, if I view it from anything but arms length, I become painfully aware of its deficiencies.
The rant was right on the money and funny as well.
