This is a bit of sensationalist non-news, isn't it? I mean, we all know how exactly every single computer software/hardware manufacturer always use "resolution-less" photographs in their ads on computer screens, cellphone screens and so on.

I think when you're specifically comparing resolutions, and you make one resolutionless and the other not... well, I'm sorry but it's not quite the same.

Earlier quoted context omitted.

I seem to recall current ads doing the same thing comparing digital cable to analog....

Same with DVD vs Blu-Ray

Can you actually see the difference between DVD and Blu-Ray?

It may just be me, but it appears that they are not much sharper than the DVDs (unlike the DVD vs VHS change) and most of it is marketing.

Planet Earth is the canonical example where the BD is instantly differentiable from the DVD.

Actually, I just realized... for the effect of what they're claiming (pixels smaller than you can see), this is a perfect comparison. Blocks to none. Sure, they're achieving it by bending the rules, but I got the impression that 300dpi played second fiddle to "your eye is unable to distinguish individual pixels."[1]

edit: their side-by-side comparison shows the correct number of pixels between the two.

It was not the high-quality of the "a" on the right that was exaggerated, it was the low quality of the one on the left.

The "a" on the right is fine, it is there to represent the kind of image in which you no longer are able to detect pixillation, going above of the supposed 300dpi limit, like what would happen on the iPhone4. On the other hand, presenting on the left an "a" with half the quality of the one on the right would probably be too difficult for people to spot the difference.

If they were fair on that slide, it probably would be interesting to analyze if people would really notice the difference or if they would just pretend they did (http://en.wikipedia.org/wiki/The_Emperors_New_Clothes). Sure thing, it would not have that much of an impact, at least until all of those people get the chance of having the new iPhone in their hands.
