Earlier this year, I was lucky enough to get to deliver a "Best of IT Forum" talk on what we than called Monad (and now call PowerShell). It was recorded and much to my surprise, this talk is now up on the Microsoft TechNete site for your viewing pleasure.
A tip of the hat to Jeffrey Snover, Monad's architect, and a great presenter whose recent blog post alerted me to the existance of this talk! I love this stuff, but I'll never be as good as Jeffrey at presenting - he's the only guy that can get nearly perfect scores at IT Forum giving a talk on a scripting language!!
