This was the month that I transitioned to HDTV. I purchased a 40" Sony LCD TV and it is absolutely incredible. Right now I'm watching Planet Earth on Discovery HD Theater -- the episode about deserts. The clarity of the images is breathtaking!
Another show that looks awesome in high-def -- believe it or not -- is Jeopardy! All I can say is this: I am hooked! I record it every afternoon and look forward to watching it in the evenings. What a fun show that is surprisingly stunning in high-def!
