The system will have pre-loaded games, applications and features (most notably the 3DS camera). One camera faces the user, while the other two are located on the outside of the system. One of the pre-loaded games, Face Raiders, allows users to shoot at funny depictions of their faces.
Other key features are StreetPass and SpotPass. When you put your 3DS on sleep mode and carry it around, you can exchange game data like Mii characters (which you can create on the 3DS or import from a Wii), high scores, and custom characters to other users you pass on the street. You can control what information is being sent out and you can exchange multiple game data at the same time. The SpotPass feature allows the hardware to detect wireless hotspots and wireless LAN access points. At these spots you can obtain free software, videos, and game data.
