After hearing repeatedly; 'The iPad will have a better display' or 'It sucks because it's not Retina' I figured it was time to break the argument down and dispel the 'Retina' myth." Fantastic post at The Verge.

The image from the lens is inverted and then must
pass through the blood vessels of the retina before being converted to an elctrical signal. This produces a a massively distorted image which must be rectified via postprocessing in the visual cortex.

In theory the eye has at least 16MP (and possibly >500MP) resolution but only the central 2 degrees of vision has accurate colour resolution.

Our vison is essentially a low resolution continuous "scan and pan" movie which is comprehensively filtered, upscaled and interpolated to produce a "meaningful" (if largely inaccurate) visual narrrative. A crude analogy is getting a drunk with a handheld VCR camera to film Lawrence of Arabia. Then postprocessing the raw VCR video using a massively powerful computer to convert the images to a 70mm wide-format film.
