Everyone has his or her own preference. I personally would rather not only watch a movie on, but simply have a screen that is a full inch bigger and has like 313dpi compared to a 326dpi display that's a whole hell of alot smaller.
Now if you're getting out a microscope and looking deep into the phone beyond what the human eye is capable of I would say the iPhone has the advantage here.
You ever been to regal cinema or carmike? ya know the movies where you take a date and buy overpriced popcorn? I would almost bet the iPhone and the Samsung both have a much higher resolution screen if you walked up and looked closely. I would still rather watch a movie with the overpriced popcorn and the hot date next to me.
The Samsung Amoled screen is just fine, very high pixel density and it's High def it's also 4.5 inches of heaven in your pocket. it's going to out do any television or projection screen. Well to your pointless standards.
Hate to sound cocky, but Wow you got like so owned it's not even funny!
