True blacks are a MAJOR benefit of Plasma TVs, admittedly, but it's become one of the few. There was a time a few years ago when Plasma beat LCD hands down. That day has long since passed. Response times on newer LCDs are fantastic (often 5ms or less). The blacks are getting blacker (though still not to the quality of Plasma), again in the Sharp Aquos or LG line. I don't mean to be a pain, I've just seen a lot of friends get Plasma TVs and be unhappy a year down the road. Even the higher quality and higher priced Plasma sets seem to fade out quickly (12-18 months).
