Sorry, no, when I say slide I'm looking at the photo of Steve Jobs with a big screen behind him showing two letter 'a's. One is heavily pixellated, and the other one is smooth in comparison - at the resolution of the slide display. Given the size of the old pixels, the new pixels should be easily visible but aren't. Of course it could be a misleading screen-grab and the slide was not purporting to show old iPhone resolution next to new iPhone resolution here. Maybe it's 'old' compared to 'perfect'. (I should point out, my participation in this crucial discussion is dependent entirely on the slowness of my compiler).
