This is better than the DS and DS lite! You can record sounds and change the sound to make it sound crazy! Or take a picture with one of the 2 cameras! The camera is only 0.3 megapixels, so I don't recommend using it that often. It can not play Guitar Hero for DS or any other Game Boy Game. It only has 1 Slot, not 2. You can also go on the internet! Or buy DSi Ware!
