Is this really a 'retina' display? I was under the impression that 300 PPI has been the border. If not, then surely the original Droid (285 ppi) was the first

  The whole Retina display thing is a) subjective, and b) down to the distance you hold the device. The '300 PPI = Retina resolution' was for a device held 12 inches away (or something like that). The iPad is held further away, so the resolution required for 'Retina resolution' is lower.

    It isn't subjective. Apple precisely defined it.

  There is some fuzziness in the 'retina' term. See http://www.tuaw.com/2012/03/01/retina-display-macs-ipads-and-hidpi-doing-the-math/ http://www.tuaw.com/2012/03/01/retina-display-macs-ipads-and...

    That is a great article that even gives you a formula for calculating it, which by the way was featured on one of apples slides during the presentation. Retina is a function of "normal" distance from face and "normal" eyesight. Those are the only two degrees of freedom. I am not sure why the author chose to guess his own numbers to see if they compare with Apples, I would instead take the formula and the fact that iPhone 4 is definitely Retina and figure out the appropriate Retina value.
