With the advent of multitasking, Apps no longer actually shut down when you press the Home button. Before long there are lots of Apps on the task bar. I regularly go to the task bar and shut everything down. Is there a simple way to close Apps completely when you are finished with them? By the way, do Apps on the task bar consume power even while the iPad is in sleep mode? Recently I was surprised to hear the sound that indicates new mail while the iPad was in sleep mode.
