So i'm going on vacation in a few weeks, and i'm going to take a DS system with me (the DS is my favorite Nintendo handheld!), but i can't decide if i should take my DSi or my DS Phat with me! All that matters for me is the battery life, the camera and things like that doesn't really matter to me (i rarely use the camera). Can you guys tell me if the battery life is better with the DSi or with the DS Phat? Thanks!
