Convenience of Function is the term I give any good product that does its damned job without a whole bunch of crap work involved. Install these drivers while plugging in this and then rub the top counter-clockwise whilst singing the Star Spangled Banner. You know the usual nonsense that comes with most electronics. My review today is on a product that is an excellent example of convenience of function. The SunBeamTech eSATA/USB 2.0 HDD Docking Station is a versatile and convenient way to access your precious data on the fly.
