Blowing Hot Air About Cold Air: Reviews of portable air conditioning units are rather vague about how loud they are. There are a few that advertise "library quiet", but I'm not so sure. Does anyone have experience with one of these machines? I need a QUIET one. If I could get down to half the volume of a window unit, I'd be very happy.
