Turning 3D off on the 3DS?

As nifty as the 3D is on the 3DS, Shigeru Miyamoto has admitted, (in an roundtable interview reported by Kotaku), that not everyone is going to keep it on all the time while playing games.
Miyamoto said in the interview: “I think it’s fair for people to say, ‘Oh yeah, for this section of the game, I’m just going to turn the 3D depth slider off.’ And, in other parts of the game, they may want to turn it on. I think that’s a perfectly acceptable way to play the games.”
The Legend of Zelda: Ocarina of Time 3D is a good showcase for the system’s 3D ability, and Miyamoto commented on this:”For a game like Ocarina of Time, in particular, if you know a cinema scene is coming up, please, definitely pop that thumb up there and quickly slide that 3D depth slider to max. It will look great.”
So are people out there with a 3DS using the 3D strategically? Concerns over battery would suggest so, as well as the possible strain from the 3D. Although Zelda, from our experience, seems a lot easier on the eyes.
