Oh yeah, lol I was told the psp has no battery life, so we just use ac adapters... Price isnt bad compared to the ds since the game quality is at least 10x better (direct comparison of Ridge Racer, heh.)
I think I flushed my money down the drain when I bought the ds, but with the psp it was worth every penny, and with the dissapointment that nintendogs left in my mouth I will be sticking to the PSP untill Mario Kart and Crossing come out.
