Yes, but then I'm going to have to manually go around my house and turn off all the lights when I leave the house and when I come back I have to turn them on manually instead of them just turning on when I open the door to a room.
Also my AC/heating automatically turns off when I leave the house and turns on when I come back, my lights automatically dim/change to a warmer temperature in the evening as it gets closer to bed time, my desktop goes to sleep when I leave the house, my TV automatically turns on when I power on the living room media PC, etc. etc.
