OK I have been doing a lot of looking in to these things and a few things to keep in mind.
LCD TV will look great with High Definition. Depending on the make / model some are going to look a lot better than others with standard TV / cable feeds.
The viewing angles for most decent LCD TVs isnt going to be an issue really. Some will have larger viewing areas than other but it all depends on how far away you sit from the set vs. size of screen
Benefits of LCD TV. NO BURN IN. LCD TVs do not suffer from image burn in. This is an issue if you intend to game on the the TV. ie. playstation, xbox , pc etc
Thats really one of the big issues
Plasma. Usually less expensive for the sizes involved. Have brighter screens deeper blacks. Supposedly better color but that isn\'t as big a difference from LCD now as it was when they both came out.
Plasme suffers from image burn in. Like the CNN logo or comedy central logo etc in the bottom of your screens. gaming etc. These usually are not rec for those purposes.
becasue the image burn in issues I would say go with LCD TV but Plasma might look a lot better with standard cable and direct tv etc
If it was me and I may be buying 1 very soon I would go LCD TV. I plan to use it for my PC Gaming, TV watching, DVDs etc. I know that standard cable isn\'t gonna look that great so I would get 1 with the idea of getting a HD-tuner.
