Do you really need a phone? Marketers don't sell needs, they sell wants.

#32It 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 r…
It's still a lie.

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.
I was a bit of a skeptic about HD - but I suspect it all comes down to the quality of the production. I was watching the BBC "Wonders of the Solar System" last night and it looked awesome in HD.

Well, looking at the keynote slide, the samples are heavily zoomed in so 'old' pixels are depicted as tens of screen pixels high. For an honest portrayal, it's easy: 'new' pixels just need to be depicted as half-as-high. Sorry, but the '300dpi' blather is complete reality-distortion nonsense. :)
Do you have the slides? I just saw the image from the guy's site. I'm not sure how much the angle of the photo will compress the distant (high quality) letter. those displays are huge, so maybe the letters are 30' apart? it's not clear how far away the camera is. They are kind of weird samples. For example the big pixel side is highlighting 25 pixels, but you could easily draw a 16 pixel square and assert the light r…
The second, black and white, example is a screen shot from the Apple website: http://www.apple.com/iphone/features/retina-display.html
The interactive examples further down appear to be realistic though.

#35I don't understand how the author of this article gets his numbers of 489 to 815 PPI. Can someone explain this?
Original iPhone = 163 PPI.
25x more pixels (5x the resolution, count the block) = 815 PPI.

#36"So you’re calling Apple out on their supposed exaggeration of the pixel density
based on… Screenshots from compressed videos?"
unbelievably dumb blog post.

Much like this current debate, it depends.
Hi-Def content has a higher resolution, but if you have average vision with an average size TV and you sit the average distance from the screen then you can't possibly see any difference.
When you're in the TV shop where they've carefully arranged the TVs so you can't stand more than a few feet back then there will be obvious differences.
Here's a nice graph to check whether you should be able to see a difference:

One interesting wrinkle is that if you're at the right distance for HD, then you're too close for any SD content you have and vice versa so unless you only watch one resolution then you either put up with the SD or the HD looking worse than it should.

#38The ratios in the demo are correct if you compare them not to the iPhone 3G but to desktop monitors at 72dpi.
But seriously, this is all to demonstrate the difference. It’s not a ‘claim’. After all, 815dpi will look the same to the human eye as 370dpi…

The graphics may not be honest, but they are indeed truthy.

Oh right, because compressing video adds information...
