The following link is one of the best
reasons why Wikipedia is a top information directory. The "open source" editors have compiled a mighty fine
and comprehensive guide to the Nintendo DS. It includes specs, release dates, how to develop for the system, and
marketing strategies to name a few. From the article: "The Nintendo DS is currently seen by many analysts to be in the same market as Sony's PlayStation Portable, although representatives from both companies have stated that each system targets a different audience. Nintendo particularly is attempting to differentiate the DS from other more traditional handheld game machines, including the PSP, and its own Game Boy line."
Excellent resource for fans, newcomers, students, and gamers alike. The only issue it doesn't address is where to find the time to play all the choice games for the portable.
