Excelent gaming device!

The Nintendo DSi Blue Console is a great hand held gaming device. Lots of new, and exciting features compared to DS Lite. You can now insert or remove a game card into the console without having to turn off and restart the system. You can now buy games through the store application installed on the console from the comfort of home with a credit card or Nintendo Wii/DSi points card for cheaper then you could find in a store.
This console has two cameras so now not only can you take pictures, but you can take pictures of friends or yourself with ease. (Must be in a well lit area for the best picture quality) Also, does not have a zoom, so this is not the best camera for for taking photographs of things at a great distance.
If you decide to buy an SD card to out into your DSi, you can upload the pictures you take using Nintendo DSi camera to your computer. the SD card can also be put into a Wii console and you can view your pictures on a television screen. 
 This console comes with the following applications pre-installed: Game Card slot, Nintendo DSi Camera, Nintendo DSi Shop, Flipnote Studio, Nintendo DSi sound, DS Download Play, PictoChat, Nintendo DSi Browser, Nintendo DSi Internet and System Settings.
This console DOES use DS, and DS lite game cards.
