The DSi it plays games, takes pictures, and plays music with features not on an iPod. Nintendo is including visualizers and one of them is based on Excitebike. The DSi also has a number of audio filters that you adjust the pitch and playback speed on an intuitive looking 2D grid. This could serve a purpose for language studies or used to give yourself a funny voice in conjunction with ten second sound bytes you can save with the recording program. Other just for fun audio filters include radio, echo, karaoke (I’m guessing this strips the vocals), and 8bit with a little NES controller icon (!). Get ready to listen to 50 Cent with 100% more beeps and bops, but only if you have your music in AAC format. The DSi doesn’t have MP3 support outside of the box.
