How do you tell that iPhone 4S has more accurate colors without actually seeing the real objects?
Maybe he has the same keyboard and has seen a can of Diet Pepsi before. It's not hard to imagine that being true. I think that the 4S shot is too red/yellow compared to the Galaxy II. This sort of comparison is pretty subjective though. (aside for evanwalsh: for the record I hate my Nexus One and have a 4S on the way)
You may be able to say "this photo looks right" but that's pretty darn subjective. Turns out we humans are kinda useless for tests like these. Past a few megapixels this stuff really doesn't matter because things like focus, lenses, and lighting are so much more important than resolution. The photos are "sharp" enough and none of these phones support mounting lenses or lights on anything. So its kind of arbitrary. Unless one of these phones has an especially shitty lens or focus or bad software, they'll probably just look mostly the same. I consider these long solved issues and don't expect much difference.
