The Nintendo DSi marks the third hardware revision for Nintendo's popular handheld device. Aside from featuring larger screens and two integrated digital cameras, one of the DSi's biggest inclusions is the introduction of the DSiWare service. Similar to WiiWare, the DSi Shop will let gamers purchase and download games from independent developers and store them on either the console's onboard 256MB of memory or an SD card. Nintendo DSi has something for everyone, containing more functions to bring you more fun!

Slow down the playback of someone speaking in that language so its easier for you to learn! You can also record sounds using the microphone, and edit them to create new sounds. 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. 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 of its predecessor. The internal rechargeable battery can still be replaced by the user at the end of its useful life of (typically) several hundred charge/discharge cycles. GBA games cannot be played using the DSi.
