If I use 1 arcminute instead, the scale factor is smaller, about 3438. So let’s convert that to inches to see how small a pixel the human eye can resolve at a distance of one foot:
12 inches / 3438 = 0.0035 inches
Aha! This means that to a more average eye, pixels smaller than this are unresolved. Since the iPhone’s pixels are 0.0031 inches on a side, it works! Jobs is actually correct.
If 65% of the population have 20/20 vision or worse how is it not a "retina display" to the vast majority of people who don't have Dr. Soneira's "best case scenario" of 20/12 eyesight, which really isn't the case scenario of known human vision.
He's not actually correct on this one. I think it's a good name, and a marketting concept that will resonate with people etc, but on a purely pedantic and anal assessment he is wrong. All this talk of 20/20 vision, your average persons eyesight, perfect eyesight etc isn't a part of the equation. What Jobs was was that around 300 (Let's give him +- 10% and go for 270 - 330 ppi was "the limit" of the human retina. The limit, not the average.
Now, if you ask me the limit of human speed so far is Usain Bolt. However your average man is probably 50% slower than him over 100 meters.
So it's a great marketing term, that whilst not being 100% accurate is probably good enough to stand up to it's claims. I think this is where Apple shine. They've taken a vastly complex subject (as proven by the pseudo-scientific back and forth arguments and discussions) and distilled it into a non technical message - 4 times more detail than your existing phone, so good your eyes can't pick fault. Compare that to some of the android manufacturers who still blind the public with science and specs. OK, Apple use terms like IPS etc during their keynotes (audience of geeks) but when it get's to the high street, that's all gone and they sell on the features, not the specs. We all know what OLED is, jonny highstreet might not, and might not care to. Meanwhile everyone understands Apple's message.
That's come across a bit fanboy, but I think it's true. There is a lot of fair discussion to be made on the relative merits of LCD/OLED, contrast ratios, colour reproduction and all that, but 95% of consumers don't care about the how, just about the what. And Apple tends to distill and clarify the message in ways everyone else don't understand is even important yet.
Tech kit eh? Reviewed by geeks, but bought by your dad.
