I have been thinking about upgrading to HDTV and I have a few questions. 1. Is there any difference in quality and lifespan between tube and lcd? 2. I am a videogame junkie- are there any types of HDTVs to shy away from due to the risk of screen-burn? Sony's PS3 will support 1080p- does anyone even make TVs that can handle that yet? 3. A friend mentioned the idea of getting a projector and a screen. Does this have any advantages over LCDs or tube TVs? Thanks for the help.
