Interesting article via Boing Boing on digital theater and how George Lucas was hoping to cause a switch-over to digital projection with his new installments of Star Wars.
From what I understand, the resistance on the part of theater owners is because of the cost of switching to digital equipment, and the probability that digital equipment will become quickly outdated and need to be upgraded frequently. I can see why theater owners wouldn’t want to get on the “built-in obsolence” bus, when the equipment they have works fine and lasts for decades.
