A method and apparatus for continuously removing siloxanes and H2O from a waste gas stream containing H2O and siloxanes includes cooling the waste gas stream in a primary heat exchanger to a temperature of greater than 2 F. For example, a mobile computing device may include an interface having a universal serial bus, a host processor to couple to the interface, and a radio module to couple to the interface. A longitudinal side wall section extends forwardly from one end of the rear section at one side of the cavity. The audio transducer can pivot on a pivot tube 142 comprising a pivotable stem to accommodate the left ear or right ear of the user.
