The last update, I was warned that an update would be rolled out to my users before it started. I don't remember how long of a delay I had, I am certain I could not schedule it to a time of my choosing BUT I could force it to happen right now on a user by user basis. Which is what we ended up doing so as to control our update time. As for the backward compatibility, I agree in general but disagree about office, or particularly about word and excel. Its support for legacy stuff is insane, and a large part of why companies with lot of legacy stuff aren't moving to another solution anytime soon.
