The Nintendo DS Lite? sometimes abbreviated DSLite, or simply Lite, 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, and more lightweight redesign of the Nintendo DS, designed to be aesthetically sleeker to complement the Wii, while taking styling cues from the Game Boy Advance SP, and to appeal to broader commercial audiences. It was announced on January 26, 2006, more than a month before its first launch in Japan on March 2, 2006 due to overwhelming demand for the original model. It has been released in Japan, Australia, North America, Europe, New Zealand, Singapore, and defined regions in South America, the Middle East and Korea. As of May 2007, combined sales of the DS and DS Lite have reached over 43 million units worldwide]

After five hundred charges, the battery life drops to roughly 70%. The original DS was supplied with a 850mAh battery, while the DS Lite has a 1000mAh battery.
* Brighter, more durable top and bottom LCD screens, with four levels of brightness. Custom designed to be more resistant to shock.
* Larger stylus, making it easier to hold (stylus dimensions: length 87.5 mm × 4.9 mm vs. 75.0 mm × 4.0 mm of the original Nintendo DS). The stylus is now also side-loaded and located below the power switch, making it easier to reach when needed.( Quoted from Wikipedia)
