i find it demeaning and Big-Brother like. Imagine your boss' robot going up and down the corridor checking to see whether you're working. I think there have been plenty of discussions here about how looking busy doesn't mean that you're necessarily productive. If my boss really cares about taking to me, s/he can either speak to me face to face, or on the phone. I'd appreciate it a lot more if I got a phone call to my desk asking me how I was doing or if there are any problem on the project he can help with (besides, is the boss expected to remote control the thing the whole day? Doesn't s/he have other stuff to do than play with the joystick all day?)
At most, I think it's a nice gadget to have for pranks at companies that can afford the $15K price tag (Google?)
