I have it on nearly always, because I have no big problem with it. But I also say it is mostly needless, Nintendo should have focused in marketing on StreetPass (which is a great feature) and probably shouldn't have used 3D if that would have kept the price lower. Anyways, some games have great 3D, especially Kid Icarus and Fire Emblem (and yes, I think the 3D in the gameplay is even cooler than in the cutscenes). But I would have liked the games anyways, so 3D is really more or less useless.
