Just released in Japan. Here are some of it's highlights: *The Nintendo DSi is about 12% thinner (2.6 mm) than the Nintendo DS Lite. *The new handheld has two VGA (0.3 megapixel) digital cameras; one on the internal hinge pointed towards the user and the second one in the outer shell. *It also has larger screens (3.25 inches, instead of the previous 3 inches) and improved speakers. *A new SD card slot is used for external storage of pictures and downloaded software and to play AAC audio. *The Nintendo DSi is able to connect to an online store similar to the Wii's 'Wii Shop Channel', called the 'DSi Shop'. *It can take photos. *Photos taken using the DSi can be synced to the Wii's 'Photo Channel'. *The DSi has five brightness settings compared to the DS Lite's four. And here are some of it's, well, not so great points: *Due to the DSi having five brighness settings, it's battery life is reduced to 14 hours on the lowest brightness setting compared to the 19 hours of the Original and Lite. *The GBA Slots have been removed, thus removing the unit's backward compatibility and its compatibility with accessories that require the GBA slot, such as the Nintendo DS Rumble Pak; as well as the Guitar Hero: On Tour and Guitar Hero: On Tour Decades grip, which is essential for those games. *All existing flash cards for the Nintendo DS and DS Lite are incompatible with the DSi.
