I have mine set to 1 minute, but I am also in the habit of turning it off manually when I'm not using it any longer. And if you go into your settings, down to Developer Options, there is a setting for Stay Awake: Screen will never sleep while charging. That I also have on, so when I'm in the car and it's plugged in, I don't have to worry about seeing pandora, etc. The screen stays lit regardless. It will still dim somewhat after your timeout setting, but not off completely.
