Professional Windows PowerShell for Exchange Server 2007 Service Pack 1 (Programmer to Programmer)

I was pleased to see a PowerShell resource for Exchange 2007. However, when I receive this it did not satisfy either of my two desires: 1) to learn more about the fundamentals of PowerShell (such as effective using pipilining), 2) better administering Exchange 2007 from the PowerShell. This book just seemed to have cherrypicked topics from a standard implementing Exchange 2007 and threw together a punch of cmdlet references. My coworker and I went through the book and came out more confused than before we started with the book. Stick with the Exchange Tech Center and the online help and you will be better off than with this reference.
