Need Your Help: Would a book like this be helpful?

I'm considering writing a new book on Windows PowerShell. This will be a significant departure from the other stuff I've written; the goal of this book will, first and foremost, be to TEACH PowerShell - not to serve as a reference. In fact, the outline of the book will closely match the outline I've been using for classes, with the idea that you cover a single chapter a day, spend some time doing exercises you're given, and so on. The order of the topics is very specific, introducing just one or two new things at a time and then building upon them.

This is intended mainly for total newcomers, so I'm deliberately not covering more advanced topics (although I won't rule out a future 'advanced' book if there's interest and demand). So, this isn't intended to be comprehensive - it's supposed to be instructional.

I also intend to pair each chapter with video snippets of the various things I'd normally demo live in a class. Not sure how those videos will be delivered - publishers hate bundling CDs with books these days, so I might just put up a Web site to host them.

So my question is this: Reviewing the outline (which I'll paste in below), is this a book you would have found useful when you were just getting started? As a complete PowerShell novice, are there any topics you would have wanted included that you don't see here?

(apologies for the formatting of the outline - Word doesn't paste well into the Web)
