This is true. That's why I pay no attention to bigger TVs and BluRay displays and all that mess. If I'm happy with what I have, it costs me less and I have more money for the things to watch and play on my smaller TV.
And every once in a while I remember the first TV in my family's house, a black and white with two clicky-click dials taht stood on a rickety metal cart, and the way we were transported by the upgrade of the giant console color TV...and I'm pretty damn happy with what I have right now.
If only we could get the old ridiculously heavy, still functioning tube TV out of the house.
