3D actually makes a lot more sense for a handheld than for a TV. With the handheld you already have the display, so you don't need to spend a few K to get the right TV, and if the 3D only works if you view it from a certain angle then that's fine too, because with a handheld you are ALWAYS viewing the screen from the same angle, but with a TV you could have people sitting in multiple spots in a room so it might create some issues.
