For your very highend consumer. After a certain point you get to the point of diminishing returns. Yeah night scenes will look awesome. But most consumers will not compare night scenes. They will be looking at the ultra-bright scenes in a darkened corner of Best Buy.
I've been holding out for the SED for almost two years now.
I have seen a couple PDP projection systems that look real good, though. I'm not completely familiar with the principle behind these units, but the result is really great looking, and not too bad on price either. They don't have a burn in problem, either.
Still, I won't get serious until I can put an SED in the mix of possibilities.
