I've had my 65" widescreen HDTV for nearly a year, and I love it... but until about an hour ago, the best picture I was seeing was from DVDs (480 lines).
My local cable company just recently started offering HD signals, so I had them come out today with one of their new fancy-schmancy High Definition Digital Cable boxes. There's not much programming available yet (

Anyone else out there enjoying HDTV? Tell me about it.
