I have used many versions of the remote desktop for the last five years. I agree that from a security standpoint, this is an excellent approach with no downsides I have experienced. I have a two minute demo available over the web for anyone that wants to see this in action.

Security and compliance mandate this shift to very mature technology. That said, I have never had a computing environment I liked better. It is truly an awsome way to work.
