Well I appreciate the response, and the list is nice, so thank you!
But - it addresses a question that I did not ask, and does not answer the question that I did ask! 
My question is: if we want to get rid of (roaming) profiles (and we do), then what are the advantages of View Persona Management over ... just simply re-directing desktop, my docs, favorites, etc ... with standard windows folder re-direction? For most people this accomplishes the major things that they like about roaming profiles.
What is BETTER about Persona Management (which involves in essence still having roaming profiles - just architected better, I think?) than folder redirection and having NO profile?
