I am a pretty big deployment geek when it comes to Vista, so most of this feels like repeat information.
The only real things that have even changed are booting from VHD, deprecation of other tools for DISM, new policies for IE8, and a few upgrades for MDT 2010.
Otherwise its basically all the same as Vista. Im blowing through the Microsoft Courseware that was posted because its telling me stuff i've known for 2 years.
