Cameras and the LCDs that love them have been in cars for a while now, but Mitsubishi has managed to eliminate enough of the LCD's excess weight to make it entirely replace the rearview mirror. A rear-mounted camera records all the action that happens behind the car then feeds it to the LCD in the front. Primarily designed for those big, hulking trucks that freak everyone out on the highway, the 7-inch LCD (the CM-7200) has a brightness of 500cd/m2, ships in November and retails for $550.
A fun idea, to be sure. I just wish a 7-inch LCD didn't cost $550, which seems a bit much.
