i actually have perfect vision. did you walk around with the iphone 3g and while looking at the screen say "gosh i wish i couldnt see all of these damn pixels"-i highly doubt it. yes if you hold the 3g a few inches from your face you can see them. but the galaxy s is nowhere near as bad as the 3g, with a 1/2 bigger screen. i had both of them at the same time(iphone 4 and galaxy s) and i think the galaxy s screen looks better. ive never seen a pixel on either one of them, but ive never held my phone 2 inches from my face. like i said i gave the iphone 4 to my wife, but she was so jealous of my phone she returned her iphone 4 for a galaxy s as well.
Comparison between the screens. http://www.youtube.com/watch?v=HJ4zrtZg5e0 For me, the iphone's high pixel density is good for reading non-zoomed in text. Not sure what else, mine isn't here yet.
