Ahh yes. I'm moving in the near future and plan to get some curtains just for that issue.
We have a couple LCDs and LEDs in the bedrooms and yeah the quality and colors are definitely noticeable. The only reason I choose plasma over LED is because one like you said, the blacks are better, as well as the fact that it doesn't get all soap opera weird. Do you know what in talking about? Walk into a Costco or best buy and look at a TV that's playing a blu-ray that you've seen before and it somewhat transforms the flow of the image. Like it's not supposed to look like that. I find it to be the strangest thing.
