Not many more... PSP is obviously competing with it like many other entertainment devices and contents are competing between them.
DS success is based around the introduction of new type of software that cater to a wide array of people.
Basically DS is a Blue Ocean product with a really good business model.
I think that DS was brought by what Iwata called , since 2003, the drift gamers phenomenon ( a contraption of the VG market with cost arinsing costantly ) as a counter measure.
Sure the introduction of PSP force Nintendo to release it quickly ( DS path wasn't the definitive DS ) but I don't think that was the mojor motive of DS release.
