No I dont think you should get it because first of all you cant use the charging dock or car charger since the cables are different. Second of all what is the point of the USB SD card reader if your D.S. doesn't use it. Last of all, you cant use the screen protectors because the DSi's screens are bigger than the DS's so it wont cover the whole screen. The only things you could use are the game cases, Carry all tote bag, stylus, audio splitter, earbuds, and wrist strap. But I dont get the point of waisting the money if you cant even use half of the stuff.
