A NEW Handheld from Nintendo : DSi

Early October, Nintendo suprises us with their brand New DS called DSi (which we don't know for sure what "i" stands for).
It has a lot of different (if not better) features than DS Lite which is :
-Reduced Size (overall) -- DSi is 12% or 2.6 millimeters slimmer than the Lite.
-Comes with an external 3 Megapixel camera and a VGA camera located on the hinge (besides the mic), directed towards the user. Picture Editors are included.
-Full music playback functionality, including adjustable pitch and playback speed. But without MP3 (it just support an infamous AAC format).
-Both screens have been expanded to 3.25 inches.
-SD memory card slot is included, and there'll be on-board memory also.
-Will ship with an built-in Nintendo DS web browser.
-DSi will allow users to download games from DSWare, a new service that operates with Wii Points -- or, as they are now known, Nintendo Points. Logging onto DSWare for the first time will grant users 1,000 free Nintendo Points. DSWare comes in four pricing categories: free (!), 200 Nintendo Points, 500 Nintendo Points, and 800 Nintendo Points.
-The Cons is GBA Slot (also known as Slot 2) is nowhere to be found :(
-Will come in lovely matte white and matte black. Begone, foul fingerprints that have taunted us so!
-And finally, it launches on November 1st in Japan, and will cost ¥18,900, or roughly $179.
