Despite having a fairly blegh launch, the 3DS has sprung back quite a bit. We now have some quality retail releases on the market, like Super Mario 3D Land and Mario Kart 7 as well as some downloadable titles like Pushmo and Mighty Switch Force!. But even outside of simply actual game releases, there have been a lot of improvements to the system itself through a couple of pretty significant updates. While a lot of this content is definitely appreciated, nothing has come quite as close to transforming the system as Swapnote has. While easily mistaken for deviantArt if you have NicoCW on your friends list, this seemingly minor application has changed what it means to own a 3DS.
