“What will you and I do?”
A third model of the Nintendo DS, called the Nintendo DSi, was announced on October 2nd, 2008. It is thinner and lighter than the Nintendo DS Lite, having removed the Game Boy Advance slot. However, this means that the Nintendo DS Rumble Pak, which was used with titles such as Mario & Luigi: Partners in Time, cannot be used. Two cameras, music playback functions, Wi-Fi, internet browser, larger screens, and a Wii-like channel interface were added. There was also a feature called "Flipnote Studio" where the player can create their own animated flipbooks. The Nintendo DSi has sold 17.82 million units, while the DSi XL sold 2.08 million units as of March 2010. 
The DSi is also able to download games from the Nintendo DSi Shop, stored on an SD Card or in internal memory. It was released in Japan on November 1st, 2008, in North America on April 5th 2009 and in Europe on April 13th, 2009. The DSi's front has a camera lens, and another, smaller lens is located where the mic was positioned on the Lite, allowing for photos to be taken with the DSi open.
A special DSi was sold on Friday, November 27, 2009 ("Black Friday") in the United States only. It came preinstalled with five Mario DSi games/apps, namely Mario vs. Donkey Kong: Minis March Again!, WarioWare: Snapped!, Dr. Mario Express, Mario Calculator and Mario Clock. It was available in the new Metallic Blue color; however, it is no longer available in stores.
 Nintendo DSi XL
The Nintendo DSi XL (DSi LL in Japan) is a recent revision of the DSi. It includes larger screens with a diagonal of 4.2 inches (93% bigger then the DS Lite and the regular DSi's screen). The size and weight increased accordingly, so that the new model weighs 50% more than the DSi. According to reports, Nintendo wants to aim the new version to older gamers who might have trouble seeing the screen of a regular DS model.
