I love my DS. But there's really only one DS game I ever bought: Advance Wars DS. It's quite good, but I keep my DS with me for a much sharper image when I play GB and GBA games (and it does have a better image display than the GBA). I also like my PSP because of the number of games that are fun on there. Metal Gear Ac!d 2, Me & My Katamari, Metal Gear Solid: Portable Ops, etc.
