I know my friends in retail won't like this column, but I've got to be honest. I have no plans to buy a 3D TV any time soon.
Keeping in that honest vein, 3D TV is impressive. I had doubts that a home theatre could challenge the sheer grandeur of a movie theatre experience when it comes to 3D, but new technology makes it possible to enjoy Up and Cloudy With A Chance Of Meatballs in your home in the way it was intended.
3D TV gives the illusion of depth by applying stereoscopic technology to what would have been a 2D image. It sounds like science fiction, but basically what it does is fool your brain into thinking you are 'in the scene' by projecting different images on individual eyes.
OK, technical details aside, to enjoy 3D at home, you'll need the TV (duh!), the source, the glasses and the cables to bring it all together.
