Even if you only have a few sites, and would like to be able to spend less time on the tedious manual tasks associated with running a Drupal site over it's entire lifetime, you will still find something of use in this presentation.

If you've looked at Aegir in the past, and would like to get a sense of the progress made by the project (two major releases since Drupalcon DC), this presentation is a good way to get a grasp on where we are heading.
