Among the hands-on tests we had at CES today included JVC's unique GS-TD1 3D camcorder. The first-ever mainstream 3D, 1080i-capable video camera is relatively bulky compared to traditional 2D camcorders but is surprisingly compact versus the usually pro-grade models that capture those images. The demo unit was mounted to a counter and thus wouldn't let us gauge weight, but we suspect it's just heavy enough to sometimes need two hands to keep steady.
