I am trying to justify upgrading to new iPad but so far haven't been able to. The only thing that may persuade me is e the new retina screen. So,how will I notice a difference when watching video? I believe HD movies joy display at 1080, so how will the 2048 * 1536 take advantage when the source material itself is currently only produced at 1920 * 1080 at its best? I am not bothered about extra resolution for browsing. iPad2 is more than clear and good enough for browsing for me.
