3D interfaces are usually worse than 2D interfaces
I've been working in AR/VR for a few years now and fairly convinced of this. In fact, beyond the OS interlace I'd say this is true of presenting most data. The usefulness of most interfaces is that they abstract something real. Part of the value of abstraction is the removal of most the extraneous aspects of a problem. Removing a whole dimension removes a lot of data that may be extraneous.Maps are one very good example of this. A map is partially so powerful because it removes a ton of information you probably don't care about. Occasionally would you like to know a house is up a steep hill before you drive there? Sure. But most of the time who cares. And if you really need elevation data, there's a special map for that. A map which actually shows you information about grade in much clearer way than even a 3D model would (being as humans are actually really bad at guessing a grade by looking at a real slope).
