The touchpad obviously has the best potential for gameplay utility, though if you have the PS Eye then obviously the light bar could do lots of things,
Hopefully devs will find a use for touchpad. Personally I would have liked to see the touchpad be a touch screen, but that would kill the battery life.
I don't have PS4 yet so I can't say anything from personal experience yet.
