Here Comes Nintendo 3DS!

As the name itself,yeah its the first hand-held to be supporting 3D.

Nintendo 3DS uses a parallax LCD, which uses structural variations in the screen itself to split the image into a separate view for each eye, creating the 3-D illusion.Its a 3.5 inch display that supports the 3D effect.

Nintendo has also added a depth slider to the side of the machine. This simple control makes it easy to "flatten" the 3-D effect until you're left with a classic 2-D view at the lowest setting. Slide the 3-D depth to zero and you have a screen that looks more or less like you average DS screen in terms of brightness, color and clarity.

The new machine is about the same size as the standard DS, and most of the key buttons are in the same place. But now there is a start, select and home button on the machine's face, and a quarter-sized flat analog stick in the upper left-hand corner. The stick's range of motion feels a bit limited, but it seemed responsive enough. Two parallax-positioned cameras on the back also allow you to take your own 3-D pictures.
