The Mini DS is just like a DS, only it's smaller, cuter and protects your games instead of playing them. Also, it doesn't support Wi-Fi multiplayer. Don't let such a mere inconvenience distract you, though. See how the game card clips in and forms the screen of the bottom DS? That's just great. We long for the day when every single container in sight is shaped like a DS, just to remind us of all the goodness locked away within our trusty little portable.
