Probably more on the move. I always get so behind on gaming that I keep my DS in my pocket for playing on my bus during my layovers. I've done that with the PSP a few times also, but the lack of suspending ease makes it far less conducive to my playstlyle. Thus, I have to play it at home, and it sees much less use than the DS as a result. So I average out to away from home.
