No...actually you've schooled nothing. You've again just pulled numbers out of your behind.
This is going to be fun. Are you ready? Of course you are, that's why you keep reading and keep coming back because you're not confident in your answers and you have some inkling of the huge dark space inside your mind.
I said:
...with the benchmark that Apple put out of 300 ppi at a distance of ~11"...
You read it, then you say:
First, of all Apple based the 300ppi number on 11" not 10.
You need to reread your stuff more than 5 times to make sure it sticks.
Furthermore, you assert a person is going to hold a 7" tablet 12.5" from their face. You just pulled that number out of your behind. Nobody in their right mind is going to hold a tablet a foot away from their face. The very notion of that is flat out stupid.
I never pulled any number out of anyone's behind. I used it as a simple example for people like you to show how a device that is effectively an in between device such as the Nexus could have its Retina ppi determined at an in between distance: in between 10 and 15". I never asserted anything, including that people would in fact hold the device that far from their face.
But from everyone measured here in the office the numbers are spot on. What about other people though? Turns out, some other people are saying the 10" for the iPhone and the 15" for the iPad are close and even spot on... that people
do hold the device that far from their face,
and even farther.
Pretty flat out stupid, eh!

Furthermore, your made up math "sticks the nexus in the middle of the iPad and iPhone. Unfortunately, it's not in the middle of the iPad and iPhone. The iPhone's display is 3.5", while the iPad's display is 9.7". Meanwhile the Nexus 7 is 7", that is not a middle point between those two sizes, thus your "stick it in the middle" makes no sense. To take it even further, your calculation makes no sense as that is not how discernable pixels is calculated.
Trying even to illustrate something in the simplest of terms is still even to complicated for you. Let's learn the A, B, Cs again.
A. The larger the screen, the farther it's held from your face.
B. The Nexus 7 has a bigger screen than the iPhone, and a smaller screen than the iPad.
A+B= the Nexus 7 is held farther from the face than the iPhone, and closer than the iPad. If the iPad has a known value (264 ppi), we can deduce that the Nexus 7 must have a greater number of ppi than the iPad under Apple's Retina scale. That this must be the case. Therefore, the 216 ppi that the Nexus 7 has right now does not qualify as a Retina display because its pixels are not dense enough at the distance it would be held from the face (more than 10" and less than 15").
To reduce you to absurdity, and to keep things really dead simple:
Using Apple's benchmark of 300 ppi at 11": if the Nexus were held at 11" from the face, it would need 300 ppi to qualify as a Retina. It has 216 ppi, 84 ppi short. If it were held an extra inch from the face, at 12"... 1 foot... which is "just stupid! and can't be so!... nobody would hold it that far from their face!..."
It would need slightly less ppi. On your incredulous take... people will hold the Nexus 7 closer to their face... which means that anything under 11" will mean the ppi will have to increase, ever widening the gap between the 216 ppi that it currently has and the 300+ that it'll need.
At every distance, there is a certain ppi a device needs to be so that the human eye at 20/20 vision cannot discern the pixels. You have failed to address hat, as it would seem you don't know what those distances are. BTW, that 15" number you threw out there, is just what many sites speculated as being the distance used in the iPad's measurement, HOWEVER, what they don't know is what ppi number is needed for the pixels to not be distinguishable and thus "retina". You know why they don't know? Because it was never stated. You can't say "Apples take off 12.4 ppi for every inch", because you don't even know what the "retina" ppi threshold is at 15" to even make that determination.
Well, by now you probably are fuming... so I'll save you the embarrassment other than to say that 15" is the benchmark distance Apple set for the iPad 3 and has it at 264 ppi.
Full stop. At a normal distance 10" as in the iPhone, 264 ppi does NOT qualify as a Retina display as calculated using the equation Apple itself endorses.

For all you know the iPad could be above that threshold just like the iPhone is above the 11" threshold. So again, I'd love to see how you intend to prove your point, considering you have absolutely no facts to back it up at all. You've proved nothing more than the fact you know how to blow hot air and pull useless numbers out of your behind. Now run along, you've done enough making a spectacle of yourself for one day.
A child is schooled once again.

Clearly, not everyone agrees with you:
The resolution is high enough that neither Brian nor I were able to identify individual pixels at our normal viewing distances. Images do look better on the new iPad however (not a resolution but rather a panel advantage).

The average human eye at the normal distance the Nexus is held from the eyes can discern the individual pixels. This is a fact. You are the exception. And I doubt anyone on here would believe you anyway: you are motivated not by truth but to simply argue.
