My opinion on the screen is as follows: Let's wait and see the screen before we try to make a judgement on it based upon 65k colors vs. 256k colors (just a fake example I thought of). Color and how things look displayed is
SO subjective so to try to quantify it accurately seems pretty silly to me, especially as a pre-release judgement.
BUT
Here is some pics I found that give a little insight into the ordeal:
Evo next to HD2. You can tell that the Evo is a little bit brighter, more vibrant and crisper (I dont think it is, but hopefully the HD2 is not in half-lit screen saver mode right before the display turns off)
Just for some more comparison:
Evo next to Desire. You can tell that the Desire appears to have a brighter more vibrant display (partly becuase it has a color background vs. a black/grey one). Also desire has a AM-O-LED WVGA screen. It is brighter and vibrant, but looks a little off and washed in my opinion.
I don't want to continue the debate of which screens are better, and how many colors the device are going to come with - I am in the wait and see camp. These pictures, although preliminary, show us exactly what we are looking at without ambiguous numbers and specifications that are subjective.
Just my 2
