For interacting with data and information, do you think having a 3-D interface would actually be more useful than the 2D style interfaces we have today?
I personally don't think so. Ultimately, interacting with information seems to work best when it's relatively linear. That is, as straight forward as possible from the source to the user. Making it 3D would add layers of complexity to it.
But I could be wrong since I've never seen a 3D interface and can't really imagine a good one. But perhaps someone reading this can think of a good 3D interface.
What do you think?
