I'd argue this conflict by using a consumers point of view.
- A lot of people have DSes.
-- This can be argued, but its pretty much supported by the sales numbers
- The games on it look "family friendly"
-- There are "Brain training" games, this always looks good to parents.
- It ain't the color "black," kinda find the color black tends to signal "this is a very complicated piece of electronics"
- The price is a looooooooot lower than the PSP.
I don't think average joe parents care about the specs, which one can push more polygons, that stuff is left for the "hardcore" gamers that know why polygon pushing power is important, why an analog nub is important, etc etc. Parents want to make their kids happy, so the DS, being marketed towards kids is a total given that it'll sell like candy. Now those games that are all "training" type, that sells to a certain percentage of adults, which just adds on more to the total market Nintendo already has with the DS. The PSP in this field fails to a degree. Adults don't really have the time to sit and play games, they usually want something thats to the point, and will benefit them. Early adults (like 20s - 30s) usually are too preoccupied with the opposite sex, college, and getting a decent job to get money, so a lot of this market is too hard to crack. Nintendo had the right idea going for the kids, and the financially stable adults, they have time to play, where the PSP is hoping to appeal to the technical savy middle age peoples, which doesn't work because theyre too busy with life. If the PSP were to turn into a phone, or a PMP that can rival the iPod, then I'd say that thing would totally kill the DS, because almost all ages always want a PMP, and everyone has a cell phone. Just my point of view.
