Just when you've finally narrowed down the decision about what kind of HDTV to buy, something new comes along and throws you for a loop. And, no, we're not talking about SED. Mitsubishi has announced that it's developed the world's first rear-projection TV powered by a laser instead of the mercury lamps typically used in other projector TVs. According to the company, the laser projector offers higher picture quality and a greater color range than plasma or LCD sets. No word on when these will be out or how much you'll have to shell out to get one.
