"I don't think I've ever seen HD anything, and I doubt I would notice the improvement."
Yeah. Right. That made me giggle.
You'd be flabbergasted at how much sharper an HD picture is.
Couple examples...
Watching a college basketball game a few years ago. Not only could you see the beads of sweat on the player's faces, you could READ, as in READ THE WORDS, of a black tattoo on a black player's arm. On standard definition, it was hard to tell that there was even a tattoo on the guy's arm.
World Series last year.
Jonathan Pappelbon in the last game. He hadn't shaved. You could see the individual whiskers on his face. As he did his wind up, you could READ the logo on the ball and count the individual stitches.
It's even noticeable when watching series like Law and Order or a sit-com.
"1. Watching television.
2. Watching sports."
Ah, I get it. You hate America.
