i think this upgrade is "ok" if you only have the PSP fat, otherwise i don't think its all that worth it. oh and bdway, the DS Lite have brighter screens, longer battery life, shorter charging time, bigger stylus size, button/mic modifications, more colors, smaller and lighter (etc) when compared to the DS fat. not that it has anything to do with this one but i kinda hate it when people spreads out false info just to prove their point.
