I like keyboard interfaces for non-spatial input over a mouse because fingers require less effort to move than arms and wrists. They can also move faster. These problems are made worse in 3D.
I see 3D being useful in 2 cases:
1) Adding depth allows more keeping of context. This is similar to zooming in and out by pinching to keep the context. But with 3D you lose less peripheral view and occlude less of the surround content. Our brains are better wired for spatial processing in 3D.
2) Fitt's Law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. By adding another dimensions we can get objects closer and reduce the distance.
