One thing I like is you don't need "negatives". Example, my Home setup:
Trigger - Wireless connected to home AP
GPS - Off
Cellular Data - off
Simply walking out my front door and getting away from my WiFi causes WiFi to disconnect, which kills the "Home" trigger. "Home" shuts off, and 3G/4G turns on automatically. I'm still trying to figure out the lowest power location method, as when I leave home I don't want WiFi running in the background if it doesn't have to.
I know this really works best with WiFi/Cell data, as one or the other has to be on. I know GPS doesn't turn back on automatically when I leave home, but that's a good thing too as I don't want it running unless I have to.
What's the point of the Defaults setting?
