    I thought retina display was as good as it gets, something like "it's the most the human eye can see"...

    I believe its referring to the iPhone 6's resolution which is about 1080P. Unless your a spec snob on small screens I think anything about 300 dots per inch is considered to be retina. I want plenty of movies on my iPhone 5 and its looks HD to my eyes.

    yeah i was curious too :D

    I think it's now they can cross the 720p threshold that even retina (on iPhones, at least) had not yet surpassed.

    They say 720p like it's revolutionary. They say 1 million pixels and then follow up with 2 million pixels (well, Phil Schiller does rather) without it sounding anywhere near twice as impactful.

    25% more CPU and 50% more GPU is meh too. Apple's smokes and mirrors presentations are falling flatter every time.

    That said, I am looking forward to owning a 6.

    See how their trickery works. Until now, Apple didn't even have a 1080p screen. As I'm sure you know, 1080p isn't new, hence why all other new devices this year went QHD. Apple has a thing where if they didn't do it first...they wait until....wait for it....the 6s and deliver a QretinaHD. Same old tech with a new Apple twist.

    The iPhone 6 plus has 401 ppi. It's a 1080 screen, as a reference point the G3 has 4 x as big a screen and 541 ppi at the same 5.5 inch size.

    Well, Apple finally went HD on their famous Retina display.
    For the 6+ only, of course, but at least they gave some people what they wanted. A big screen that was 1080p.

    It's a fancier version of the normal retina display, some technology was tweaked a bit. By doing this, it delivers a better viewing experience.

    But it doesn't matter. I was okay with Retina.

    The moniker relates to the use of a dual domain pixel display, which only a few other phones (e.g., HTC One and HTC One X) currently offer. The technology improves viewing angles.

    Anandtech has a short write-up on the technology:

    but they're both bigger phones though so obviously you would've had to double the amount of pixels anyway.

    The term retina HD is quite meaningless.

    Retina HD = "Android circa 2012."

    I just wish the 4.7 was 1080.

    Iphone 6 has the same ppi as an iphone 5S so there is no difference in resolution between retina HD on iphone 6 and retina on iphone 5S. It's only HD because it meets the number of rows it needs to be HD but in reality, the 6 screen is no more high resolution than a 5S. The 6 plus screen has a higher PPI and so that does have a higher resolution.

    A marketing term used to differentiate the original iPhone 4 & 5 screen resolutions with that of the iPhone 6 and 6 Plus. It's basically used to help those who don't know technical details.

    HTC One, Android, had 1080P on a 4.7inch in 2012.

    Matters not to me though, I'd rather have the better battery life of the 326ppi display.

    Thats what I said you silly goose! :p

    If Apple put the 1080 screen on the 4.7" iP6, they could call it Eagle Eye Retina HD Maxx for all I care. I just want the PPI goodness.
    iP6+ will have the best battery life of any iPhone. I just wonder if it will have faster processing to chew through the extra pixels.

    You said Retina HD = Android 2012..

    I was merely pointing out that android was FAR ahead of Retina HD already... in 2012. ;)

    But in all honesty, there are more aspects to display quality, than mere pixel density.

    Back when the iPhone was 4" do you honestly believe you'd see a difference between 640p and 1080p with the same pixel density?

    If you wanna play the resolution game, Apple had above-1080p screens WELL before Android ever did.

    That said, if apple offered to put the HTC One display in the 4.7inch iPhone, you'd bite their arm off.

    Not all screens are equal.

    Ah, if only Anand was reviewing this year. Hope Anandtech give it a decent review.

    Its funny you should say that. I do not like the displays of ANY AMOLED screen, I don't like the display on the HTC One either...unfortunately.

    AMOLED does not have uniform sub-pixels and the displays always look grainy and I can see it. Oddly enough, I prefer the iP5 display to a Galaxy S5 display. I haven't looked into if they've rectified the AMOLED screen blotch issues, but I won't be revising AMOLED again. (I do like what Moto does with Active Display though).

    I can see the digitizer on the HTC One. They appear as faint 45-degree horizontal lines. I can see it with light images and light scenes in video. I can see it any time there is white on the screen.
    Nobody could see the difference in resolution if the PPI remains constant. That's what Apple is banking on with the iP6. I was merely commenting that a PPI spec bump would be welcomed, as content (visible digitaizer aside) does look better on the HTC One.

    Seems simple, Retina (>~320 PPI) on HD (>720p) screen.
