lol at the "quality/resolution of the screen" being "totally meaningless" to you.
Thats just about the most asinine thing I've ever heard. Why would you pay as much as you might for an iPhone if these sorts of things are meaningless to you?
The retina display is a game changer, plain and simple. I remember the first day I used it after 2 years of iPhone 3G usage and let me tell you, it makes a difference. A huge one. If you want to throw your money away thats fine but most of us care about what we get when we're paying thousands of dollars over the course of the contract to use it.
