I came pretty late to the DS platform and bought a DS Lite primarily because it was the last DS to be backward compatible with the Gameboy Advance. I had too many games from the Advance that I still wanted to be able to play on the newer system.
I've been a longtime fan of Nintendo handhelds. They're well supported by game developers, often backward compatible and one of the few handheld options on the market. I've never liked their screens - it always seems hard to get the right lighting conditions to really see anything. But they are the primary handheld developer out there.
Nintendo DS Lite - Technical Specifications
The Nintendo DS Lite 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, 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 initial release in Japan on March 2, 2006 due to overwhelming demand for the original model.

DS Lite -vs- original DS
A larger model of the DS Lite was an unreleased alternative to the DS Lite. It was ready for mass production but Nintendo decided against its release as sales of the DS Lite were still strong. Instead Nintendo prepared the DSi and released an "XL" version of that console a year later. This larger DS Lite featured an increased screen size of 3.8 inches (9.7 cm) (slightly smaller than the DSi XL's 4.2-inch (11 cm) screens) and lacked the wide viewing angle of the DSi XL.
