r_reddy,
Welcome to the forum, and thanks for considering Samsung.
The 7 Series and 8 Series has the Internet Suite of Yahoo widgets, which will be adding applications rather quickly in the next several weeks. The 6 Series is a great television, but does not have the additional widgets.
The 8 Series also has 240Hz processing, whereas the 6 and 7 Series has 120Hz, and is the highest in the series.
Those are the major differences. Did you have any other questions regarding these?

Can some one please tell me what are the differences between the 6 and 7 series LED TVs from Samsung. I intend to buy a 46" tv and do not know the difference betweeen the 6 and 7 series except for the pretty high difference in price. Also. is there an 8 series in the LED as well ? If yes, What additional features does that have ?
