..(at least as I see it) it's more about convenience. As in with a movement of your hand active switches when you enter a room, sits down at your work place or in front of your TV-screen. It's a tool for preferences.
Seen from security perspective it's lacking in the same way (and more so) as finger prints, face recognition etc: it's too easy to replicate.
