this post is mainly aimed toward Randuin because he has both PSP and DS. I was wondering what the actual battery life on each is. I have heard that for a DS it is supposed to be between 6 - 10 hours, and i have never really heard anything other than speculation of 2.5 - 3 hours for the PSP. I realize that it varies depending upon what you are doing with it but i would like an average. If you do not have a PSP or a DS please do not answer this, because i would like an answer from someone who actually owns one and not something that you have read on the internet.
