No, I would not "of" been doing that. I just don't think 3D is useful for phones because it wouldn't provide any tactile feedback that we require to make use of inherently useful technology. Forcing features that the masses do not require, aren't cognizant of or will use after the novelty wears off isn't the way to proceed into the future of technology.
So, if you were presented with a mobile phone, that showed a 3D solid looking image, moving in realtime of your girl/boy friend standing on the screen, you could look around as if it was an actual miniature person standing there.
Or perhaps a solid image projected up in the air of a model of an item you were thinking about buying, you'd not be interested?
