Hello, I have a question about the new iPod Touch... On the news article it says... I have seen this in other places before as well but I can't work out exactly how it is better? I looked on the tech specs and the iPhone 4/iPod 4g both have the 960x640 screen and the 5's both have the 1136x640. I know I am an idiot but can someone explain how the screens mentioned are actually better? Thanks!
