The majority aren't saying that the iPhone 5 is HD, just that HD resolution wouldn't make a difference on such a small screen. Do you disagree?
I agree. It's pointless to watch videos on a 4" screen therefore I guess HD is not necessary.

Not if they switch to IGZO.
IGZO can display a static image (like the iPhone homescreen) without using any power, as it doesn't have to constantly refresh like other displays. In other words it would use power to push the image once, then that's it until those pixels change again.
It's supposed to be highly sensitive to touch and able to pack in really high resolutions as well.

That's wrong. IGZO displays still use power to show anything because you obviously need pixels emitting light to see anything. IGZO displays are not E-Ink displays, which have true zero power consumption for static display. IGZO displays operate like any normal LCD display panel. The IGZO part is actually just referring to the type of semi-conductor material used for creating part of the display.
From http://en.m.wikipedia.org/wiki/Indium_gallium_zinc_oxide
" Indium gallium zinc oxide, IGZO is a semiconducting material, jointly developed by Sharp Corporation and Semiconductor Energy Laboratories, which can be used as the channel for a transparent thin-film transistor. It replaces amorphous silicon for the active layer of an LCD screen, and, with a forty times higher electron mobility than amorphous silicon, it allows either smaller pixels (for screen resolutions higher than HDTV) or much higher reaction speed for a screen.

"Sharp during CES 2013 was telling visitors to "brace themselves", as the company was showcasing the very first IGZO panel slated for North America. IGZO is a different technology than what's used in panels today, as it's capable of displaying a static image without the need to constantly refresh, thus saving power and battery life."
I was probably wrong about it using no power to keep pixels illuminated, that was just a guess on my part, but it doesn't operate the same way as other LCDs because it doesn't need to keep refreshing to display static images.
Later on it says:
"Sharp also had on display several smartphones using the IGZO technology. As previously stated, the standard display is constantly refreshing the screen, thus smartphone batteries typically last only a day. But with IGZO, static images such as the stationary home screen aren't refreshed, thus extending the battery to around two days."
It's clearly some kind of beautiful magic
Disagree. This is classic Apple loyalist denial when they don't have something the competition has. You are missing 200,000 pixels on the iPhone 5, which causes display artifacts on 720p video. This is a significant amount of missing pixels.
Saving power by minimizing the refreshing of the IGZO based transitors is totally different from saying that IGZO displays use no power to display static images. You are wrong.
Your forgetting the fact that most of the power draw from lcd's is it backlight, not the pixels themselves.
Also the cpu and gpu have to render whats on the screen.

Sharp claims that a tablet they are creating achieves 2.5x the battery life simply by using an IGZO display instead of another technology.

"Ultra low power consumption: IGZO can maintain the onscreen data for a certain period of time without refreshing the data, even when the current is off. This helps cut back the power consumption to achieve longer battery life for mobile displays."
This means that an image is pushed to the display, then the power can be shut off completely for an undisclosed period of time and it will still display the image.

I don't think you get the physics of light emission and the conservation of energy. Just stop. You make my brain hurt.
Yes, but not the backlight. IGZO transistors do not create their own light like OLEDs. A backlight is still required. Turn the backlight off and you'll see nothing (though the pixels on the display will still be "on").
Yes, it's much more power efficient than traditional LED displays, but it's not what you're thinking.
You are wrong, there is a major difference. The iPhone 5 is only 1136x640 = 727,040 pixels. The bare minimum to be considered HD is 1280x720 =921,600 pixels. This means that the iPhone 5 is missing 194,560 pixels, far short of being HD. This means that on the iPhone 5, you get display artifacts when you watch 720p HD videos since it can't display it at the correct resolution.

Higher quality camera on FaceTime will transmit more data. Of you're using cellular then you'll go through your data plan faster, and not everyone has high speed wifi to make a 1080p FaceTime session run smooth.
Um, what about the back camera as mentioned by bonskovsky? That has been HD since the introduction of FT.
^ That's not even possible. If its already 720, you might as well make it 1080. Come on
why are people feeding trolls
Contrary to what a lot of people have said in this thread, PPI is not everything. Apple hasn't made pixels "invisible", they can very much still be seen.
Just look at the star button in the App Store, it's very clearly pixelated.
