With rumors of 2gb of RAM on the larger iphone and a measly 1gb on the smaller one I'm starting to think that if I get an iphone at all it will be the larger one. I am fed up with reloads and the like. I have a worry however. I knew when I heard 1080p resolution for the big screen when apple usually uses weird resolutions that something was up. Now I hear all this talk of downsampling. I've read the commonly linked articles but I'm near hopeless currently when it comes to understanding these things. Will hardware downsampling have a negative impact on performance? Will the screen look like right old poo? Basically what does this mean in terms of quality and performance, and is it something to consider? P.S. will the difference in contrast ratio be noticeable? I.E. the difference in sharpness from the retina mini to Air, or not noticeable?
