[citation][nom]jkflipflop98[/nom]After Leap and Kinect PC come out, the mouse and keyboard are done. Yeah, you dipshits are raging right now, but think about it. Your buttons on your keyboard are simply coordinates on a flat x-y plane.[/citation]
Not quite, you cannot beat accuracy of input from the keyboard (comparing to voice), and keyboard has tactile feedback that neither touchscreen or kinect have.
for mouse, unless you don't have the desk to put the mouse on, using mouse uses least energy to navigate. The physical distance you hand travel is far less than using the touchscreen or kinect.
In some situations, sure, kinect can beat keyboard and mouse.
