I try to know most of the people in the complex I live in. That's the kind of guy I am. Anyhoo, there are a couple of "everyman" types that I talk to and use as sounding boards. Sacd DVDA? Never heard of them. But, the one guy actually sought me out and asked about the "new" kind of dvd's he'd heard about......Blu something. I said, yeah, Blu Ray. He said he'd seen it advertised on TV and wondered what it was...I gave him some of the backstory on the format war etc etc. He was pretty interested. But then I mentioned the new discs won't work on his dvd player.........he IMMEDIATELY LOST INTEREST.
Oh, great analogy, Clint........
