AMOLED is far superior to TFT. Some people posting here have never used AMOLED before they are just trying to make themselves feel better about the Evo not having one.
My Incredible has AMOLED and there is NO difference in viewing in direct sunlight compared to any TFT screened phone I have used. I have compared side by side with many TFT screened phones. Whoever made up the misinformation of AMOLED being poor in sunlight is dead wrong.
AMOLED does not have a backlight making black levels amazingly 100% black since the LEDs are simply off and there is no LCD to leak backlight light like on TFT. Also colors are amazing on AMOLED since there is no backlight to wash them out.
AMOLED uses less power. When the screen is mostly black the screen uses almost NO power at all since most of the LEDs are off and there is no backlight to suck power.
