OK. I'll bite. There's frustration because all this has been hashed out and the complaints are typically from biased sources.
A. More pixels mean smoother curves. Compare an iPhone 4 to an iPad and you'll see less jagged edges. I don't want more pixes just to show more and have everything smaller. The iPhone 4's retina display is stunning.
B. Since my eyes are not like a crab's and always point in the same direction, well, almost always, I read one e-mail at a time and scroll up or down to see more. If this is too much effort, change the settings and see nine at once.
C. Comparing the price of a car to the price of an iPhone, I'm not surprised a car has more robust features.
D. Uploads to YouTube are already at full 720p. Are you holding the phone the right way to get 720p video? One way it does and the other it doesn't.
