I don't trust digital downloads. I know if I replace my 3DS I can switch everything over, but what if I completely destroy my 3DS and/or my SD card? I like using game cartridges because if I go to my friend's house and bring my games but not my 3DS, I can use theirs. Plus, I've always like being able to see my collection of games. I think I'd play a digital copy less, for some reason. I'm not using my 3DS much right now anyways, because I've beaten most of the games I currently have (except for the 3DS Harvest Moon and the games I'm doing a second play-through of). At least I'll have the new Pokemon Mystery Dungeon game to keep me busy while waiting.
