I do have a htpc now and am considering LED LCD for a main screen.
My main gripe with manufacturers is that they do stupid things to sell things to people who don't know any better. Like putting glass on LCD screens...hmmmm it used to be non reflective and you just made it as reflective as any plasma on the market...way to go genius. Oh wait now they put motion interpolation in plasmas...when smooth motion wasn't much of an issue with plasmas to begin with yeah, I'll spend extra money for that.
All those crappy extras that drive the price up....I don't need my tv to have a camera (now I'm scared to watch adult movies cause my tv is taking pictures of me), I don't need my tv to have internet....I have a computer and if I didn't, I wouldn't buy a tv this expensive...I'd buy a computer. Why can't they just make a tv with a good picture, calibrated out of box to be close to decent, with isf calibration controls, and leave out all the BS. What a concept, a tv designed to watch tv on.
