Well, the Economist didn't even scratch the surface. HD DVD for computing? With greater storage capability, actual and potential, for Blu-ray? And more computer device manufacturers joined in early on Blu-ray. They just saw Microsoft and made one hell of a leap. Intel? Really, they'll sell chips either way.
HD DVD's best chance is in home movies, or perhaps overseas. Even if they become a niche product in the U.S., they might profitably continue overseas, especially in India. Unless the French get a wild hair, again, I suspect Europe will lean toward the winner in the U.S.
Still, both might survive. We'll see.
