Unless you've been living under a rock, you've probably noticed that it's a great big 3D world out there, and it's getting bigger every day. The latest arrival is Toshiba's 55WX800U, a 55-inch 3D LCD TV with edge-lit LED backlighting. At $3,300 (list), the 55WX800U doesn?t come cheap, but it does have the usual array of features we've come to expect from a top-of-the-line set.
