We've had a Verizon sales person join here recently and spoke about his annoyance at customers not purchasing insurance. It has also transpired that he is very anti iPhone too so perhaps it is a general feeling from their training? It could of course be that he just doesn't like them and enough to tell a mac friendly site all about it. The point above about the extra commission from other branded devices make sense and its the same in any business. Sale people rarely sell you something unless it profits the company they work for better than yourself.
