[citation][nom]icemunk[/nom]The term "Retina" IS a marketing ploy, and it is shown when people try to compare what consittutes a pixel when comparing super AMOLED and LCD. Either way, they're all nice displays. Some people like OLED, some people like Apple.[/citation]
It is not AMOLED specifically which has the issue. It's Pentile displays. It has nothing to do with the discussion over retina display, but Pentile actually doesn't have full pixels. Every other device does.

The average is 12 inches, according to the study I linked and backed up by the scientific quote I posted. The 13 inches you quoted was in reference to tablets, and was not me or Watcha saying that devices were held at that distance. It was mentioned because you disagreed with the accepted 15 inches plus viewing distance, and the point being made was that the iPad would qualify for the 'retina' label even if it was held as close as 13 inches.
At the 12 inches, the PPI required is 286 PPI.
[citation][nom]v1ze[/nom]"For example, researchers found that the average working distance for text messages was 14.2 inches (36 centimeters)"Looks to me like 2 distances were referenced with one of them being mine and neither being the distance Apple mentions[/citation]
The article provided two different averages. The average when text messaging was 14 inches, the average when web browsing was 12 inches. You necessarily must take the smaller of the two distances because users on an iPhone do use it for web browsing, thus the screen must be suitable at that distance. That distance of 12 inches giving a necessary ppi of 284 is the correct number, going by the study I referenced, and it is not the number you gave. You incorrectly took the larger of two numbers to try and prove your point, which you shouldn't have. If a lorry has to drive under two bridges of different heights, when working out whether it can or not you need to take the lower bridge, not the higher one.
This distance of 12 inches backs up Apples claim of 'around 300 ppi' and it also rules out the Nokia N900, which is entirely consistent with all the points which have been made. While I personally always thought Apple had claimed that people hold the phone 'a foot' away, or so, whether you believe it is 11 or 12 inches doesn't change anything here, and I'm not sure they ever specifically said 11 inches. Watcha provided values for 10 inches, 12 inches, etc, so all bases were covered. The N900 is still not a retina display by any definition, and the iPad at 264 still is.
The PPI is noticeable up to the point the device qualifies as a 'retina' display - for most users. This is the very definition of retina, and the reason why it came into being - scientific. It's not a plot because it's backed up by logic - Apple boasting effectively that they have reached as many pixels per inch as an average user will ever need. 'Retina' as a term is a marketing term, but it's not cunning or misleading at all. This is why the N900 has a visibly lower quality screen.
