Thats pretty funny calling those things "Game changers" oh yea and the battery too lol
Firstly i will say the new iPhone 4 is a nice looking phone, and is a moderate improvement over previous models, but to say nothing on the market can touch it is just silly
First off "Retina Display" is another of Steve Jobs CON JOBS it's another frikkin lie!! lol he claims the display is better than the human retina?!!
Dr. Raymond Soneira runs DisplayMate Technologies, which makes software to test display quality. He also knows more about digital displays than just about anyone I know - and I know some pretty tech-savvy folks. This morning, Dr. Soneira shot me an interesting email regarding the so-called "Retina Display" of the iPhone 4. To clarify: a retina display is one whose resolution meets or exceeds the maximum resolution the human retina is capable of resolving, assuming perfect vision.
This is a bit tricky, since the eye doesn't have "pixels" and the resolution required to match the human eye's capability depends on the distance from your eye to the display. If you sit four feet away from a 50" 1080p television, you'll see pixels. If you sit 100 feet away, you won't. The distance between any two visual elements is a matter of how many pixels per "arc degree" of vision it covers. Dr. Soniera's email, in full and unedited, is as follows:
The iPhone 4 has an outstanding display... and I'm glad that Apple resisted the emotional rush to OLEDs because they still need lots of improvement before they will be ready to compete with the highly refined IPS LCDs. The iPhone 4 display should be comparable to the outstanding IPS LCD in the Motorola Droid, which I tested and compared to the Nexus One OLED, which was trounced by the Droid.
Steve Jobs claimed that the iPhone 4 has a resolution higher than the retina - that's not right:
1. The resolution of the retina is in angular measure - it's 50 Cycles Per Degree. A cycle is a line pair, which is two pixels, so the angular resolution of the eye is 0.6 arc minutes per pixel.
2. So if you hold an iPhone at the typical 12 inches from your eyes, that works out to 477 pixels per inch. At 8 inches it's 716 ppi. You have to hold it out 18 inches before it falls to 318 ppi.
So the iPhone has significantly lower resolution than the retina. It actually needs a resolution significantly higher than the retina in order to deliver an image that appears perfect to the retina.
It's a great display, most likely the best mobile display in production (and I can't wait to test it) but this is another example of spec exaggeration.
...
So there you have it - some math from a display expert showing that, while the iPhone 4's display is certainly exciting and probably represents a step forward for smartphones, it may fall short of Apple's claims of meeting or exceeding the resolution of the human retina.

but of course fan boys will love to tell friends that "my phone has "Retina Display" lol
now the other things. 720p recording is hardly new, most recently available on the HTC EVO 4G the FIRST 4G phone available on the market. which boasts a much bigger screen, an 8 megapixel cam versus iphones 5, a front facing 1.3 megapixel cam for VIDEO CONFERENCING or "Face time" as Apple calls it, and you are NOT limited to ONLY face time between 2 iphone 4's over wifi no 3g or 4g support unlike the HTC. and you can't even use your phone as a mobile hotspot allowing up to 8 devices internet connectivity
and battery wise, sure it has a long lasting battery. but if it dies you can't swap it out with a fully chargred back up like you can with almost anything other than an Apple product
so in reality, there is nothing revolutionary or really new in the new iPhone, except for maybe the "gyroscope" or whatever fancy name they gave it
but it is a nice phone and many people are gonna love it. you will never convince an apple fanboy otherwise.
wonderful!! so as long as you and the person you are calling are both on an iPhone 4 and both are connected to WIFI, what good is it?
HTC EVO 4G lets you do that over a 3g or 4g network as well as wifi and even better the HTC evo is available NOW. well unless they are still all sold out.
read what you want. i share information from many sources about many things
it's up to you to decide what you make of it...i don't really care
how many signs are fitting for u?
The iPhone 4 is what the iPhone 3Gs should have been. Apple strung everyone along with a nearly nothing upgrade from the iPhone 3G.
That was awesome, great mailbox.....
Apple has the kind of following that Harley Davidson does.... how many companies inspire tattoos......
Anyone have a RIM tattoo... didn't think so.

Soooo going back to my pre press days as a technician .... it is known after 300 ppi the retina cannot differentiate any further.... so why is it a lie..... ohh right the doctor told you .... u mean the research doctor in computer science?

Yes this man with these credentials told me that... i believe him
Dr. Raymond Soneira is President of DisplayMate Technologies Corporation of Amherst, New Hampshire, which produces video calibration, evaluation, and diagnostic products for consumers, technicians, and manufacturers. A research scientist with a career that spans physics, computer science, and television system design, Soneira was a Long-Term Member of the Institute for Advanced Study in Princeton, and a Principal Investigator in the Computer Systems Research Laboratory at AT&T Bell Laboratories.
Soneira, who possesses a Ph.D. in theoretical physics from Princeton and has been studying displays for 20 years, said it was inaccurate to measure the resolution of the eye in terms of pixels, because the eye actually has an angular resolution of 50 cycles per degree. Therefore, if we were to compare the resolution limit of the eye with pixels on a screen, we must convert angular resolution to linear resolution. After conversions are made, a more accurate “retina display” would have a pixel resolution of 477 pixels per inch at 12 inches, Soneira calculated.

Hmmm...whos more credible....Steve Jobs and canucklehead or Dr Raymond Soneira? tough choice
yep and 2 or 3 years before that it was a Nokia. things change and it's about to happen soon again
A big difference between Harley fans and Apple fans is Harley guys can take apart and re assemble their bikes
the girl with the tattoo is Apples number 1 fangirl, she would have Steve Jobs child if she could
That's the difference between Apple and Android.
With Android, nerds take pretty girls and photoshop Android logos on them. Apple has actual pretty girls who use and love their products.
Ain't that the truth!
What's even funnier is that as easy it is according to Apple fanbois to do things with their stuff, there are still so many amongst them so 'tech challenged' they have to pay people to upgrade their Mac and even load up their iPods....
LOL, very Ghetto.....I can't imagine a RIM tattoo but how about this one...

Hmmm looks like all the magazine and prepress companies have been wrong all along with the 300 ppi resolution as well as all those silly folks at Canon, Fuji and Xerox ...... oh and droid boy ... http://www.gearlog.com/2010/04/google_admits_to_downgrading_i.php since the doc is your star witness ....The average human retina has five million cone receptors on it. Since the cones are responsible for colour vision, you might suppose that this equates to a five megapixel equivilant for the human eye.
But there are also a hundred million rods that detect monochrome contrast, which plays an important role in the sharpness of the image you see. And even this 105MP is an underestimate because the eye is not a still camera.
You have two eyes (no kidding!) and they continually flick around to cover a much larger area than your field of view and the composite image is assembled in the brain - not unlike stitching together a panoramic photo. In good light, you can distinguish two fine lines if they are seperate by at least 0.6 arc-minutes (0.01.Degrees).
This gives an equivilant pixel size of 0.3 arc-minutes. If you take a conservative 120 degrees as your horizontal field of view and 60 degrees in the vertical plane, this translates to ...
576 megapixels of available image data.
Curiously - as a counterpoint to this - most people cannot distinguish the difference in quality between a 300dpi and a 150dpi photo when printed at 6x4", when viewed at normal viewing distances.
So: although the human eye and brain when combined can resolve massive amounts of data, for imaging purposes, 150dpi output is more than enough to provide adequate data for us to accept the result as photographic quality.
But don't forget that women have more cones and men have more rods - I kid you not.Therefore the ladies see colours brighter than gents but can't see as well when it gets dark.
There was a report today that Apple has bought enough parts to deliver 3M a month......
I'm guessing they think it will be a hit.
