Eh, I'm an enthusiast when it comes to audio/video, but do I care about HD-DVD or Bluray or the format war? No. And here is why... The source media + price = worst satisfaction per dollar spent on the planet for me. I guess I'm the kind of person who doesn't take care of his stuff, but I prefer to think of it as I don't have OCD when it comes to my disc collection. I finally realized that it wasn't worth it for me to invest in CDs, DVDs, HD-DVDs,etc... when they all eventually get scratched and ruined. And I don't want to have to back them up... I have far too little time as it is to waste more cataloging, preserving, and worrying about a disc collection. The day audio/video is offered in a format I can go swimming in the ocean with and use to fight off a shark attack, I might think about making another purchase.
Also, I really don't get the whole I need to own this movie thing... there are very few films produced that I would feel would be worthwhile to actually own (excluding children's movies if you have kids).
As for HD in general, TV programming and PPVHD movies are what I am concerned with....
