The Nintendo 3DS isn't the company's first foray into 3D. That honor goes to the dubious and best forgotten Virtual Boy. That said, the 3DS is the first 3D handheld video game system that actually looks like it has a chance. Early adopters or "3DS Ambassadors" as Nintendo likes to call them, shelled out $250. Now, with the price drop to about $180, is it worth buying in?
