We moved to this model after we upgraded some of our systems to Win7 64bit. The GN4000 drivers did not work with Win 7 64bit. The Jabra Link 180 works great with the 64bit systems and installation is simple, just plug it in and let windows install the driver. The only things I don't like about it is the weight. The Jabra Link 180 is very light and is easily bumped around on the desk. Also, the manual switching between computer and phone can be extra work but nothing to complain too much about. This is a good product. We have about 5+ deployed now and looking to deploy more.
