The problem with Leap is that to do anything remotely accurately for a moderate period of time takes an huge amount of effort moving your arm in mid-air with only visual feedback. It will be marginally worse than using a wii controller to type on a screen keyboard, as that includes tactile vibration feedback as you hover over keyboard letters. In the video it struggled at typing a single word on a keyboard.

The device looks great for toy/demo cases like google earth and fruit ninja. There aren't many normal use cases where you would need slow, low accuracy pointing or gestures from a distance that isn't already covered by wii, kinect or a laser pointer for example.

Remote control is already solved by remote controls with buttons and smartphones connected to a tv. The tactile feedback increases the speed of usage so much that no touchless device will ever surpass.
