PSP. Even though it does have some problems. Like it being not as well built as the DS. But then. PS hasn't been the most sturdy system. The fact is. PSP can play music and videos. As well as having a large amount of games at launch that I am actually interested in. Aside from the two that DS launched with. The graphics are superior to that of the DS so far. No games have utilized the DS' graphical capabilities yet. So PSP for me.
