Like any IT Pro, you have what appears to be million tools and strategies to get your desktops deployed.  A very well written guide was just posted to TechNet that gives in-depth guidance on how to get Windows 7 and Windows Server 2008 R2 deployed using just a few, targeted strategies for specific scenarios.  This guide outlines the four main deployment methods as well as the IT Skill level required, the infrastructure that helps determine your choice, as well as strategy and tools guidance.  This is an amazing guide that I feel every IT Pro needs to read.
