The Nintendo DSi is 12% slimmer, sports 3.25-inch screens, does away with the GBA slot but adds an SD card adapter (download from the web and load off the card), allows you to play music and has two 3-megapixel cameras (one on the inside, the other on the outside). The DSi will become available in Japan on Nov. 1 for 18900 yen ($180) and will also be able to surf the web and catalog your photos in a flipbook or port them to the Wii. Nintendo will also launch a DSi Shop where you can download titles for free, or purchase them for either 200, 500, or 800 points (DSi comes with 1000 points free).
