Not to mention keeping spare parts around for when something breaks, or having to drive out to the DC to fix/replace the thing that broke or won't restart. Hell, even something "simple" like managing the warranties for the gear you have is no fun at all. People tend to forget all those little things when espousing the evils of the cloud, but I'm here to tell you that they all add up and they are all a major pain in the butt. Cloud gets rid of all that.
