The Nintendo DSi is a high-powered handheld video game system in a sleek, folding design-loaded with features designed to create a unique gaming experience. Like the DS and DS Lite before it, the DSi features Nintendo's trademark stylus-driven touchscreen technology, but determined to make portable gaming simultaneously larger and smaller in all the right places, Nintendo has also created the DSi with significantly larger screens and an even slimmer body design than its earlier cousins. Other features include the ability to snap photos with built-in cameras, edit and send them to friends, play back your music with Nintendo DSi Sound, or browse the Internet with the Nintendo DSi Browser. From playing games to just playing around, the Nintendo DSi does it all. The DSi's Two Digital Cameras: The most noticeable feature of the slim Nintendo DSi system are its two cameras - one camera is situated on the external body pointing away from the user, and the second one points at the user when the device is flipped open. As the first truly interactive digital camera in a video game system, the DSi Cameras feature 10 different interactive "lenses" that can manipulate your photos, offering an easy way to take and share your photos with family and friends. The cameras also present people with unprecedented ways to interact with their games, and in the process provide developers with a new tool to devise creative games and experiences. If the touch screen gave Nintendo DS a sense of feel and the microphone allowed it to hear, the two cameras give Nintendo DSi the sense of sight. DSi Sound: Another enhanced feature is the Nintendo DSi Sound application, which serves as both an interactive voice recorder and music player that allows users to play with their music while they listen to it. Users can access different audio filters or control the pitch and speed of recorded voice or music files to alter voices or change the tempo of a song. The mic is located between the two screens when the device is flipped open, and there is also a stereo headphone output that lets users listen to music saved on an SD card, even with the screen shut. The DSiWare: In the world of software, Nintendo DSi will be the platform for the most relevant and fun on-the-go games and applications. The Nintendo DSiWare application will populate Nintendo DSi with software that can be downloaded using Nintendo DSi Points directly to the portable system, just as WiiWare has with Nintendo's Wii console. Developers big and small are invited to create software that makes use of the properties and functions of the hardware. Nintendo DSiWare games and applications will be available at a range of values, starting at 200 points. Games and Backwards Compatibility: In addition to downloadable games, Nintendo DSi is able to play games made specifically for the system and sold at retail. The system can also play most Nintendo DS games, and will have access to a library of more than 850 titles originally made for that system. As an example of the quality of games that DSi players can expect to see both from both Nintendo and third-party game developers, at the launch of the DSi Nintendo is also releasing Rhythm Heaven. A wildly popular rhythm game in Japan, where it has sold nearly 2 million copies since its release in mid 2008, Rhythm Heaven features catchy tunes, charming characters, and a wide variety of rhythm games as it makes maximum use of the DSi's functionality.
