To 3D or Not 3D?  The hot topic at this month's Consumer Electronics Show in Las Vegas was the coming oversupply of 3D televisions. This technology is moving from the movie theater into the home. There is not a lot of 3D content today so these screens will also show 2D, HD, Blu-Ray. For 3D, special viewing glasses are required. As these products are rolled out, the question for the consumer is simple – “why buy?” Price today for a 42” model is  around $10,000. Sony has stated that by 2012 30 percent to 50 percent of its TV sales will be 3D.
