You should see how thick some of the oleds are today lolYeah. years ago, the only thing that really changed was that TVs got larger (and heavier). In 2000, I bought a 37 inch TV (huuuuuuge for the time) that weighed 180 lbs. Today, the 50 inch LCD weighs 35lbs and is considered small'ish.
Today, my 7 year old 50 inch is far better than my 15 year old 47 inch and I'm sure that even the cheapest new TV will be better.
