Nintendo DSi vs Nintendo DS lite?

A Nintendo DSI has a completely different layout, design and features than a DS Lite. The Nintendo DSI contains an outer and inner camera, a different user-friendly and better looking software, the colors available are different for it (they're not quite as light as the DS Lite), and the outside is not shiny. Also, there is no port for putting in Gameboy cartridges. The DS Lite is the older version of a Nintendo DS, and the only difference is that its shiny, comes in different colors, and it contains a Gameboy port. The DS Lite is not as expensive, especially if you buy it used, but at this point, both models are old enough that you should be able to get them at a cheap price.
