Strivin To Be Green

So after almost everyone (except for me) went out to buy a new TV to accommodate for the digital tv signal, we are now told that there is an even better new fangled TV that we just have got to get. The 3D TV. At the Consumer Electronics Show, this technology is on display in the Samsung HDTV LED 9000. It sports a thin screen and includes a 3D processor, 240 MHz refresh rate. It is said to be more energy efficient than plasma or LCD TVs. My question is, just how environmentally responsible would it be for people to ditch their brand new digital TVs just so Hannah Montana or Chuck can leap into living rooms? Or do the makers of the digitals know something we do not about planned obsolesce?
