The built-in ability to set up sequences based on various triggers is very useful.  When I stick it in the car dock, it automatically turns on bluetooth, connects to my BT speaker, turns off wifi and turns up the volume. When I arrive home, my location is detected and BT is turned off and wifi comes on to connect to my home network. As I walk into the office, the tethering app is launched and ring volume is adjusted all without any user intervention. 

Very cool.
