Samsung Galaxy S vs. HD2 vs. Zune HD
As we learned at Samsung's Galaxy S event in New York City last night, Samsung is very proud of their Super AMOLED screen. We took it for a spin and compared it with the old HTC HD2 and the Zune HD. The contrast and black blacks are comparable to the Zune's regular AMOLED screen, but the Samsung Super AMOLED screen seems much nicer under the lights. It looks to have deeper contrast as well.
