That is a little like saying you "only" won based on the score. Resolution is the game. Having perfectly crisp letters on my iPhone 4 is so nice. Really it beats all the other categories you are talking about. I don't know if AMOLED can be made better, but if I'm seeing individual pixels with my naked eye, than the screen loses to the iPhone.
This is such nonsense. If there was a shred of legitimacy to this reasoning (that iPhones (or any phone) needs 300 ppi) then why is it an iPad, at 8 times the surface area (or more) runs at almost exactly the same resolution as an iPhone 4 but is perfectly good (great even)? You do know that people used computer monitors that were 17" or more diagonal at 1024x768 and were perfectly happy with it, right? So if an iPad is great at 1024x768 and 9.7" diagonal why does anyone think they're making a valid point by pooh-poohing any pixel density lower than the iPhone 4 has at 3.5" diagonal?
