I've been observing the introduction of HD-DVD and Blu-ray with some befuddlement, because I just can't convince myself that a new format is needed. Of course, I'm not a technodweeb kind of guy: as I noted recently, I have the same Sony Discman I've been using for over a decade, and I still have the same shelf stereo that I've been using for a year less than the Discman. I didn't get a DVD player until 2003. I'm not afraid of technology, but I never get this sense of urgency about it.
Anyway, here's an interesting article about HD-DVD and Blu-ray. Its tone is very skeptical.
