Couple of interesting things about Windows 7 such as the System Debugging Recorder. Enables end users to record actions they perform.  Also Powershell 2.0 enables remote command execution for admins.

Application virtualization looks neat where you would be able to say put an implementation of Office 2007 on a server and the user could run Office without having it on their PC, or it gives the impression that it is on their PC.  If you combine that with folder redirection and roaming profiles, you could enable folks to log on to any machine and have it look the same as the one in their office.
