C|Net Editor David Katzmaier did an article on this that's worth a good read, even if it's a little dated:
I am very interested in this plasma TV based on the CNET review. However, I read that, in spite of the Engery Star rating, the TV consumes a considerable amount of power.
I read the information about power consumption on CNET and understand that plasma screens use more ebergy than LCDs and LEDs, but the annula cost doesn't seem prohibitive for plasmas.
Now I am not greenie. I just don't want something that is going to cost me a lot of money to watch. Can anyone comment on this issue?
