The magic number

This is something that has been bothering me for a while now ever since Apple announced the iPhone 4 two years ago. 

You see, if you calculate the pixel density of the Retina display on the iPhone 4 or the 4S, it turns out to be 329.65 ppi, bit higher than the 326 ppi figure that Apple touts. Now Apple is not the one to downplay anything, which is why this struck me as odd. 

Yesterday, Apple announced the new iPhone 5 with a display resolution of 1,136 x 640 and 4-inch diagonal size. Once again Apple is claiming 326 ppi and this time they are correct, the actual pixel density is 325.97 ppi. 

Why do you think Apple would use a smaller number to describe the pixel density on their previous display, that too a number that is curiously exactly the same as the pixel density of this new display that they launched two years later? 

It seems to me then Apple has been toying with the idea of using this exact display before, but they probably didn’t as it would have been too much of a jump for the developers from the 480 x 320 resolution display on the 3GS.

It made sense then to use 326 ppi for the previous Retina display, cause if they had used 330 ppi it would have seemed a step down when they would eventually upgrade to this longer display. Makes me wonder then why they didn’t use it on the 4S last year. 

Of course, I could just be high on all this cocaine and imagining things.
