The main purpose of a slide is to help the audience remember your message. To keep the audience focus on you, make sure your slides don't contain much text and certainly no bullet point lists. Your handouts, on the other hand, need to be useful to the audience when you're no longer there to explain your message. For this reason, your handouts should contain much more detail than your slides.
