Much potential, little benefit

The possibilities for 3D input are fantastic and especially in the context of virtual reality (Oculus Rift) is a rapidly aware the potential of such an entry.
Unfortunately there is a lack of benefit from the 3D to draw input to software. Who wants to replace his mouse will soon realize that little is to be gained with the Leap. The 3D> 2D conversion takes in my eyes the meaning of the input device.
Only proper 3D programs (for example "light little adventure", "Derigo" or "Block 54") can feel a how powerful the capabilities are. Unfortunately, these are rare exceptions, and most titles grab only touch on concepts which can be just as well or better use the mouse.

I have (the App Store) even bought a few titles on Airspace and then ultimately used with mouse or gamepad.

Who has the money for a cool gimmick than can confidently access, is already a fascinating toy and something to show it to friends. Anyone looking for really practical use is more likely to buy a dust collector. But still, the device is not a year on the market and I hope that the situation with the advent of virtual reality will change again.
