The interview sheds some light on the design decisions that combined to create the DS Lite, with each explaining the reasoning behind weight and the new screens. The two speak of how the DS Lite's top screen needed to be sturdier, yet fit in the overal smaller package the team was aiming for and when no pre-existing piece of hardware met their criteria, they partnered with a LCD manufacturer and went into test mode, putting several variations of the top screen through a rigorous testing regimen. The final outcome, which some of you already know, is one brilliant piece of technology.
