I am looking for info regarding the Chromebox. Can it be left on 24/7? My father is disabled and would be unable to access the power button - currently he is using a Logitech Revue but the Revue is no longer being supported and I'm trying to find something to replace it. (A notebook or tablet won't work, as he has vision problems and needs to hook the computer to a large screen tv to use as a monitor.) Thanks!
