I'm just happy as long as regular flashcarts won't be the death of my system, since it's a pain to carry around all my games.
Btw, I've tried the 3DS OoT at an event, and it was awesome indeed.
Mine has a very slight wobble to it. This is completely unnoticable during gameplay though, as I don't swing around my 3DS like a madman.
It works great while playing Faceraiders. I have no complaints.
