The Nintendo DSi is the third iteration of the Nintendo DS handheld. It was first announced during the Nintendo Conference on October 2, 2008 in Tokyo, Japan.

The Nintendo DSi is about 12% thinner (2.6 mm) than the Nintendo DS Lite. It has brighter picture than DS Lite console. Also the new handheld has two VGA (0.3 megapixel) digital cameras, one on the internal hinge pointed towards the user and the second one on the outside of the shell. It also has larger screens (3.25 inches, up from 3 inches) and improved speakers. The power switch has been replaced with a power button, as the original DS had, now located next to the bottom left side of the touch screen. The DSi has five brightness settings compared to the DS Lite's four; however, battery life is reduced to 14 hours on the lowest brightness setting compared to the 19 hours in its predecessor. The internal rechargeable battery may still be replaced by the user at the end of its useful life of (typically) several hundred charge/discharge cycles.

A new SD card slot is utilized for external storage of pictures and downloaded Software and to play AAC audio. The front slot for Game Boy Advance cartridges has 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. The removal of backward compatibility also prevents games such as Pokémon Diamond and Pearl from accessing saved data stored on GBA cartridges. The DSi has 256 MB of internal flash memory. Photos taken using the DSi can be synced to the Wii's Photo Channel.

You can still play DS games on this DSi console, all DS games are free region 100% guaranteed.
