ok well my kids have the ds they bought them last year one of my daughters friedn got the dsi. From my understanding the dsi can do more and you need to download the game to it. If you have a game cartridge for a ds it won't take unless its for s dsi the cartridges are different from what my daughter says I hope I helped plus one other thing to consider. Do you want something that is more up to date or something thats older and may be out in another year or so. I don't know. Good luck
