title: Need clear understanding of Home vs Back events
body: <p>I would like to know the "idea / use" of the home versus the back button. I mean obviously the  home button takes you to the home screen and the back button takes you to the previous screen. What I am trying to understand is what the users / development community expect. </p>
  
  <p>In other words when a user hits home in my application should I handle that event and terminate the application? Is that what the user has grown to expect or just the opposite? </p>
  
  <p>Same for the back button. Do users expect the screen being departed from to be lost much like a web page would be?</p>
  
  <p>What I am getting at is trying to make sure my app behaves consistent with what the user community has grown to expect.</p>
  
  <p>TIA
