iPhone 4's resolution resolved
When Steve Jobs introduced iPhone 4, he claimed that its "Retina Display's" tiny pixels exceed what the human eye can differentiate. "It turns out there's a magic number right around 300 pixels per inch, that when you hold something around to 10 to 12 inches away from your eyes, is the limit of the human retina to differentiate the pixels," Jobs said.Begun this week the war has.
Plait explains the math behind pixels and resolution. Specifically (and I'm paraphrasing liberally here), two nearby objects observed from a far-enough distance appear as a single object. Plait uses the example of an oncoming vehicle. Is that one headlight or two? Is it a car or a motorcycle? As it get closer, the lights separate and you recognize it as a car. This is because, Plait explains, over a longer line of sight the two objects closer together have a smaller angle separating them, making them harder to distinguish from each other.
So what does this have to do with the iPhone? Well, Jobs claimed that our eyes can't differentiate between neighboring pixels presented on the Retina Display when viewed from a distance of 12 inches. Soneria claims that isn't true, and Plait did the math to find out. He concluded that Soneria's numbers assume a user with perfect eyesight. Since the vast majority of people lack perfect eyesight, Steve's claim is true: Their eyes will fail to resolve those tiny pixels at a distance of 12 inches.
Technically, both men are correct. Steve may have exaggerated since those with perfect vision will see pixelation at 12 inches. At the same time, Soneira is nit-picking, as the vast majority of users do not have perfect vision.
I hope this, as Plait says, "makes things clear."

I would say that steve jobs claims that there will be no pixilation from 12 inches away is probally true but not just because of the higher pixle count. I believe it will be a combanation of pixle count and the new glass screens themselves.

Everyone's vision is different, but what he says comes close in actuality, at least according to the articles I've read. After all, it's just marketing hype and he did NOT say that it is more than any human could see ever, period, end of story.

"Don't give me this lame "Retina Dispaly" naming bullshit, give me the true facts about what it is and what it can do."
Ok, here.

Saw this on another article and had to laugh...
In response to the claims that the "RetinaDisplay" is "false advertising":

"Android marketing is false advertising. Phones aren't actually androids!"

YYYEEEAAAAAAHHHHHHHHHH
Oh look, Jordan is whining again. It never seizes to amaze me how some people constantly visit website where they disagree with basically everything and spend all their time arguing with people. Jordan seems to be one of those people who hate Apple and their products, het they frequent Apple-related websites just to tell everyone how they hate Apple and/or disagree with those who hold favourable opinin of 'em.
June 11 2010 at 5:22 PM Report abuse Permalink rate up rate down ReplyAm I the only person with perfect vision out who can't see neigboring pixels at a distance of 6 inches let alone 12 inches on my original Iphone? I have contacts that correct my vision to 20/10. Without my contact lenses I have amazing near vision and I can barely make out neighboring pixels on my original iphone holding it next to my eyeballs. I can see them on my computer screen but as we all know thats about 71 DPI. I can see pixels on TV screens if I press up against it too and see the different pixel pattern/shapes of various models of televisions. Is there some image out on the web I can use to see these neighboring pixels at 12 inches or pressing right against the Iphone? Nothing I see on my home page or dock on the phone shows me these pixels evryone is saying they can resolve. Am I just pixel blind?

That the new iPhone gets over 300dpi is incredible. Computer displays are usually at about 72dpi, Newspapers are at around 150dpi, and high end art magazines top out at around 300dpi. It's an amazing resolution and it's the highest in any mobile device right now. Repeat: THE HIGHEST. The argument from the Android fan base changes and talks about Steve Jobs' false claims, but if they can see the individual pixels on the new iPhone screen, the screen on their EVOs must be driving them insane.
The screen is incredibly dense and the colours and contrast seem to be fantastic. AMOLED screens are hard to see in direct sunlight and don't have the same viewing angles. The only benefit that they have over what Apple's using is battery life, and Apple's made this a non-issue by giving us a larger battery that gets 10 hrs of video (that's twice as much as the EVO, by the way).
The target from the Android side is moving. The iPhone has a better screen so now they say the EVO is better because it's larger? I didn't know larger screens where the measure of a good "mobile" device. Is an 8" screen a better mobile phone, then? Because it sounds to me like it becomes less mobile. Should the battery of a mobile device only last half a day, because plugging it in sounds like it would become less mobile.
There are things you'll have to give up on both sides, if you're choosing platforms. The Google side is more open and if that's your priority, there are some great phones to choose. Usability and stability, form factor, screen quality, battery life, and design are also good measures for others and I think the iPhone trumps Android every time.
It's funny because those who tinker and want to rearrange their icons and leave large gaps on the screen and hack their phones are the ones calling the iPhone a toy. Meanwhile, I'm letting Apple deal with the details and I'm calling, sending texts, surfing the web, using apps... real honest to goodness work. Not getting geeky with the insignificant stuff.
The iPhone is still the best platform if customizing your phone isn't your absolute top of the list feature.

Yes, I was tired of having to keep low res files in iTunes for playback on my iDevices. Now I can keep one larger file for Screen and portable use...
