I can't see the screenshots either, but I can comment on the question.
I've had a CRT-based widescreen monitor capable of 1920 x 1080i since 11/2001. There is a world of difference between HD and SD (and even ED, which is 480p = DVD recordings today).
I get my HD content over the air for free, basically my local channels in Philadelphia, PA. The difference is staggering and once you have HD, you will never go back. People who have never seen HD come over and are completely blown away.
I'm clearly an "early adopter", but the future of TV is definitely HD.
