I've always used the 3D even on my o3DS. But I'm really glad I have a n3DS now, I can finally sit in a more relaxed position when playing games without losing the 3D effect and seeing double instead. I got so used to seeing double on the o3DS that my mind kind of just adjusted to it and it didn't bother me that much, so when I got out of the sweet spot in the middle of a game it often took me a few minutes before it started annoying me and I readjusted the position.
The super stable 3D is not perfect but it's pretty close (when it readjusts there is noticeable flicker and if I put something in front of my face, it loses track of my face and goes immediately back to double vision, I would like if it kept the current 3D adjustment for at least a few seconds after it loses track of my face)
It really is what the 3D should have been like all along.
i love the 3d. i'm sad that pokemon just uses it in battles, but overal if it has good 3d i'll use it, mario 3d land + zelda + smash bro's, poke rumble world i love all of those with 3d never play them without =)
I cannot use it, i have binocular sight, that means i cannot look thru both eyes at same time, it could be super cool, but i cannot see it right, i can just see double images everytime.
So, obviously, my vote is NO.
i am using 3D Mode on my New 3DS only on Kingdom Hearts 3D and sometimes on few other games like Rune Factory 4.
but never on games like Monster Hunter 4 Ultimate (terrible)
