AMOLED displays are beautiful. Primarily, when they're black, they're completely dark. The contrast ratios are just outstanding. Likewise, they have a much broader color gamut, with far more saturated colors than are possible with traditional backlit screens. The downside is that the Android software stack and graphics chips can't deal with this amazing color gamut. They just make all the colors more saturated. It's cool looking, but it's not correct. There's also a greenish color cast. Now that I'm running CyanogenMod, I can at least fix that with their "color calibration" setting. Very nice.
