Millions of Americans bought their first HDTVs between four and seven years ago, because that's when prices for 40" - 50" sets started dropping below $700. Those sets are obviously between four and seven years old now. Are new ones so much more wonderful that it's time to get a new HDTV? Not necessarily. Alfred Poor, long-time display technology expert and senior editor for aNewDomain, has some insight here, which he shares with us in today's video. There's obviously a lot more to discuss about TV technology advances (such as 3d) that we didn't get to today, so look forward to another discussion on this topic in two or three weeks.
