I thought it was going to be a cute video on a mouse stalking his owner, but it's actually ear rape of a mouse stalking someone.

I don't like this future... I doubt it'd be that useful in a normal setup though, the mouse doesn't vibrate as much when it's on a mousepad, right?
Also remember seeing something about your phones knowing what you're typing based on the sound of the key presses, don't know how that works though. Maybe they create a matrix of possible key places from the difference in volume of each press? Scary stuff.
