Pretty straight forward thread here (I hope!)
My girlfriend wants to know which one I'd rather have for a Christmas present, but I'm not really sure what to tell her.
So, I'm basically looking for opinions from people who own (or know a lot) about each of these hand-held systems. I've done some Google research but I'm still not sure what to pick -- it seems to come down to graphics (PSP) vs. gameplay/variety (DSi).
