moh bettah, easier to read comparison
The Nintendo DS Lite (sometimes abbreviated NDSL/DSL or DSLite, sold as the iQue DS Lite in China) is a dual-screen handheld game console developed and manufactured by Nintendo. It is a slimmer, brighter, sleeker and more lightweight redesign of the earlier Nintendo DS model. It was also designed to be aesthetically sleeker to complement Nintendo's Wii, and to appeal to broader commercial audiences.
