Richard Smith posted a new entry to the Deployment Guys blog today (http://blogs.technet.com/deploymentguys/archive/2008/03/20/sccm-2007-and-microsoft-deployment-toolkit-video-walkthrough.aspx), walking through the full "Configuration Manager 2007 with Microsoft Deployment Toolkit" scenario. Be sure to check that out.
Also check out the video (http://edge.technet.com/Media/664/) that Jeremy Chapman, Joey Snow, and I did that is now up on the Technet Edge web site. We chat about a variety of Windows deployment topics, including Windows Vista SP1 and Windows Server 2008. It's really hard for me to watch it - it's bad enough to see videos of myself giving presentations at conferences, which are taken from a good distance. This one is an extreme close-up in comparison. (See my stark office in the background. We had a flood a few months back caused by a water leak on floor above us, so everything was packed up while they cleaned up the mess and I haven't taken the time yet to unpack.)
