Its less "often" and more "convenient". If you need to make a chance, reboot, shutdown, etc, is it easier to open your browser, login to DO, find the droplet, etc? Or two clicks in the menubar?
Can't imagine not trying to login to the server and doing some investigation before just doing a blind reboot I agree with parent, and prefer this http://fitztrev.github.io/shuttle/ Best of both worlds (and works with all hosts) only thing you lose is the 1 click reboot/shutdown
And you would be surprised how often blind reboots happen (sometimes you don't get to make the call).
