The main point is that the PSP has an audience of young males, while the DS has a universal audience.
Considering that, the PSP has done pretty well.
Unless Sony start making games like CookingBoy, Quiztime or MyBarbieWorld they will never get the same sales as a DS.
They've been trying with HannaMontana etc, but its hardly been a big push.
Sony is seen as a tech mans company. Nintendo is seen as a family company.
Big difference.
