In shameless self promotion the video of the talk I did on PowerShell and SQL Server has been posted to the web. I haven't watched this as I just can't bring myself to sit and watch myself for an hour but the session evaluations were pretty good. Therefore I think the odds are pretty good you'll get something out of this session, especially if you're new to PowerShell. A bunch of other talks have also been posted. Here's the landing page for the videos.
