Sony HDTV's are the best. PS3 helps the sales of HDTV's.

I wonder what the useful life is of a HDTV? Could someone fill me in on both the Useful Lives of LCD and Plasma TV's?

Plasma's have been on the market for 12 years. LCD's have been on the market for 7 years.

 seriously, even in an off-topic thread about TV's you manage to talk both about sales and the ps3..
