Scott Hanselman is a superstar presenter.  Here is a link to a video of presentation he gave to the Beantown.net users group in boston that focused on Windows PowerShell.  Even if you are a longtime PowerShell user, I encourage you to watch this because Scott provides some great ways to think about things.
