It doesn't matter; the onus is not on me to find this information.
Apple posts detailed specs for most of the components of their computers/devices. They post operating specs like max and min temperatures, max altitudes, etc; esoteric things that most people will never look at, but which is READILY available (and by that I mean right there in front of your eyes when you look at
apple.com/macbook/specs.html, for instance.
Why does Apple post things like minimum temperature specs for the very few people who would consider using their Macbooks at <-13F, but not the ISO specs for their screens, which affect every single Macbook user? Moreover, they post the specs for the cinema displays, but not for any other product. Odd, unless they know that people buying displays will tend to be more litigious about this issue, and therefore Apple is simply covering their asses for the displays, but could care less for the other products.
The end user does not have an infinite requirement to dig for information that the company is willfully withholding. They could post the specs if they wanted to, but they dont because MOST people wont make a fuss, and those that do will be put off by the ISO specs that Apple quotes. Only a very few people know their rights as a consumer, and one of these rights is not being held accountable for details of purchase that they were not aware of or should reasonably been aware of. And the fact that Apple posts the specs for the displays but not for other devices suggests that it is not impossible for them to give the consumer this info. THEY choose not to, so I shouldn't have to dig for that info.
Sorry, but no matter what the ISO standard says, unless Apple makes that information widely available to its customers BEFORE purchase, I'm not going to be held accountable for following the spec.
