Most websites right now do not have this responsive design for different display sizes and types, and it remains unclear how many will adopt it, so it doesn't apply in most cases now. I know that some online website publishing sites (like Squarespace.com) do use it on the back end, but they're the exception, not the rule.
And, about your confusing posts, you said this "But still, its not just about pixels or watching movies. 1080 will still give you more viewing area in the web browser and maps etc so its not pointless."
Then, you said this in a later post "For escape the Galaxy S3 has a 4.8 inch screen with a resolution of 1280x720. My nexus 4 has a 4.6 inch screen with a resolution of 1280x768, because my phone has more pixels on the width it can fit 5x5 apps on a screen on the app drawer, the S3 can only fit 5x4. Screen size only affects how big everything is, not how much you see."
This shows you clearly don't understand how pixel density and vision work. Apple (and everyone else making high pixel-density screens) are giving us screens that have pixels that cannot be distinguished by the vast majority of viewers. After this saturation point has been reached, there is no detail or smoothness to be had or gained by going from 1280 x 768 to 1930 x 1080! Physics man, physics.
No matter how much you want it to be so, it isn't.
