Plasma or LCD for my living room? I don't care about burn-in. I do care about cost and I want to get bang for my buck. I will get surround sound so that doesn't matter from the TV. And do LCDs and Plasma both do HDTV with my cable box and have digital inputs? Also, what if I went EDTV vs. LCD? Don't get too technical with pixals and screen speed etc./xyz and all that jazz b/c I don't care, keep it simple please.
