A major part of the youthful avoidance of voice command is its finickiness. Voice command is getting better, certainly, but even the most modern, advanced systems can still get things laughably wrong--or worse, do them slowly, and since we're well-versed in several forms of standard text-entry, we tend to choose that just out of a desire for speed. Key example: Microsoft's Kinect is one of the most incredible gadgets we've ever seen, and its voice command is so advanced that it can pick out separate voices, or even the direction the voice is coming from. But performing simple tasks is still a bit slow. Say you're watching Hulu on your Xbox 360. You want to pause it. You have two options: pick up a remote and hit the pause button, or say "Xbox," then perhaps "XBOX" a bit louder and more forcefully if it didn't hear you the first time, then wait for the playback menu to pop up, and then say "Pause. PAUSE." It's cool, in theory, and fairly fast when it works smoothly (which is quite often), but I certainly find myself reaching for the remote instead more often than not.
