It came about because children would keep the 3D on and get migraines from playing for super long time. So Nintendo made it as a cheaper and alternative for them and people not caring about the 3D which is pretty neat I will say.
Fair warning; I can’t remember if they stopped carrying charge cables with that one, so make sure to look. Apparently in Japan, they don’t come with one, which seems really stupid, but since there are a lot more dedicated Nintendo Stores in Japan.
