Pity the early technology adopters in this world. Just as they have accepted the fact that three years ago, they paid more than $5,000 for a 42-inch flat-screen HDTV that now sells for close to $1,000, a new image starts to coalesce in front of their eyes — an image so real, so lifelike, it could only be … a 3-D TV. It may be back to home entertainment’s square one for those first adopters, thanks to consumer electronics giant Sony. Company CEO Howard Stringer said Sony will start selling Bravia televisions with three-dimensional viewing capabilities next year.
