I'm 39 years old, very slightly near sighted Hey - me too! At that range, I can just barely perceive single-pixel transitions if the contrast is very high I can still see the vague indications of pixel boundaries in fine fonts on my iPhone 4, if I concentrate and squint my eyes. But I can't really see individual pixels with clarity. And while I don't use one daily, I honestly can't tell the difference between that and the 30% larger pixels on my Galaxy S. I think we're well beyond the point of diminishing returns I have both (well, I have an iPhone 4 and my wife has a Nexus S). Text on her Nexus S looks terrible compared to my I4. It's OK if I haven't been using my phone for a while, but if I pick up hers after using my I4 for a bit, the lower resolution and those terrible 2 colour pixels really stand out. White backgrounds look speckled, gradient transitions have banding, pure colours look impure, fine lines look stippled, and there are no smooth curves. Again - this is only when looking at her Nexus S after staring at my iPhone 4 for a while. The Nexus S is a fine phone otherwise - responsive, flexible, intuitive. And the OLED screen is arresting in low light conditions. But otherwise the screen looks noticeably worse than the I4's. I didn't think that I had especially good eyesight - very slightly near sighted, as you said. But if you want to keep using your Samsung S, I wouldn't recommend spending any more time with an iPhone 4. Or just do yourself a favour and get this Galaxy-Nexus-Prime.
