It is better than dealing with the salesmen selling things that just are not possible. One time I was given a day to implement a magic iPhone detection algorithm. It had to distinguish from iPod touch, and somehow this was to be done based on "network characteristics". So during an emergency meeting the salesman said "It can just be done from the MAC address, quit whining." Well after a while we managed to get hte customer happy, and the salesman was told "Next time, if you aren't sure talk to the programmers first". The programming team was told to expect a new hire that "knew what he was doing".
