Nintendo 3DS
Manufacturer	Nintendo
Released	February 26, 2011 March 25, 2011 March 27, 2011
Predecessor	Nintendo DSI

The Nintendo 3DS is the successor to the Nintendo DS. It has 3D technology without the need for glasses. The screens use a parallax barrier system. New with this DS is the analog control stick, gyro sensor and motion control. It is set to be the home of the upcoming title, Animal Crossing: New Leaf.

Features

1. The 3DS has a gyroscope (tilt sensor) allowing it to detect movement of the console. This gyroscope is used for some 3DS games, most prominently the built-in one known as "Face Raiders." It has an analog stick, so controls can be more free. It has, like the DSi, two cameras: a regular camera atop the 3D screen, and two on the lid of the 3DS allowing for 3D pictures.
2. The 3DS has two screens: the lower screen, which remains a regular touch screen, but the top screen has been shortened and lengthened, and it serves as the 3D screen for the console.
3. There is a slider on the right side of the console allowing one to adjust the 3D depth so it can be focused. One can also turn the 3D off, for example if one is blind in one eye, the screen would appear as two transparent images overlapping one another.
4. From watching the gameplay footage from the Kid Icarus: Uprising trailer, one can see that there are vast improvements to the graphics.
5. The 3DS is also able to play 3D movies, on the top screen.
6. It is backwards compatible with the Nintendo DS and DSi.
7. It has a Virtual Console with Game Boy, Game Boy Color, and Game Boy Advance games.
8. Carrying the 3DS whilst traveling allows you to swap data with other 3DS', called "StreetPass."

Manufacturer	Nintendo
Released	July 28, 2012 July 28, 2012 August 19, 2012
Predecessor	Nintendo 3DS/Nintendo DS
Successor

This version of the 3DS has 90% larger screens than the original Nintendo 3DS and additionally features longer battery life. It also comes with a 4GB SD card as opposed to the previously included 2GB card. Also, the Start, Select, and Home buttons are completely redesigned to fit the longer screen. The bigger screen minimizes the reflection in light, and has more advanced graphics including the 3D. The shape of the 3DS XL is smoother as opposed to the rigid shape of the original model. The placing of the stylus is on the right side of the 3DS and is no longer on the top left side, making it easier to access.
