I have the 50inch online exclusive Samsung 6580 model. I like the TV but without local dimming flash lighting can be a problem. I was thinking of going to the LM7600 55inch to gain local dimming. The only feature that matters to be is that i would lose Pandora. Maybe not the biggest deal but it is the only app i use. I want to stick with LED since plasma and CFL put off too much heat(my room turns into an oven). Any suggestions?
