Are you talking about battery life?Originally Posted by Shoden
If so, I don't know what you've been reading but the DS will out do a PSP on a full charge by about 5 hours.
It's well documented that the PSP battery will last around 6 hours. And even that depends on certain conditions.
As i've said in other threads on this topic, the PSP is a good system with lot's of features. The problem I have with it are battery life, dead pixels on the screens and dodgy square buttons. None of which Sony seem bothered about fixing with there, thats how it is take it or leave it attitude.
I have a DS and i'm pleased with it. It's got a good battery life, around 10-12 hours, built in WiFi for multiplayer, and it can play GBA game's. As for the DS game's Mario64 DS, Wario Ware Touched and Yoshi Touch and Go are the best one's avilable at the moment.
I think both machine's are good but imo, Sony rushed the PSP and released it before it was ready. The DS is the better piece of kit for me.
