Packt just announced the availability of Microsoft SharePoint 2010 and Windows PowerShell 2.0: Expert Cookbook book by Yaroslav Pentsarskyy. I was one of the tech reviewers of this book. I really enjoyed reviewing this content and learnt quite a few new things on using PowerShell for SharePoint administration tasks.
