I got a chance to sit down and chat with Scott Hanselman for 20 minutes or so while I was in Portland.  Scott was a totally gracious host, and took an opportunity to introduce me to another tool that he raves about (and I never tried), PowerShell.  For the uninitiated, PowerShell is a command line and scripting environment.  Think cmd.exe, but with first-class support for the .NET framework class library, XML, WMI, and much, much more.  After Scott demoed it for me, I went back to my hotel and played with the shell for a few hours.  Although my need for it has been limited, I'm madly in love with PowerShell.  This is powerful stuff.

I can't say anything about PowerShell that hasn't been said already, so do yourself a favor and check it out.  While you're at it, check out some of the info on Scott's blog, his podcast on the subject, and his recent post about the PowerShell IDE.
