Thanks Sandeep!
We are planning on using AC in the Cloud. The thought of using fixed desktops in each room has been a consideration, but I've resisted that idea because i thought i would use Dragon for those times when i need to step out of the room and dictate (right now I do that for physical exams and when a personal letter is requested). After reading some of the other forums about the problems with Dragon and AC, I'm now reluctant to try Dragon.
Thanks again for the input!
