Industrial design

One thing that can really get me cooking is industrial design.
Today it is the plastic little flipp on the cat-5 cable connector that after some time, at least when it is connected to a laptop that is carried around the flat, breaks off. It really grinds my gears. I have not counted, but I believe that I currently have at least five cables that are broken. The cable is probably designed to be stationary, you plug it in to a router and a computer and then you leave it, and then there would be no problem. But I can not be the only one that use a cable connected to a laptop right? It baffles me that the connector has not evolved into something sturdier. (One reason might be that most people use a wireless connection and hence circumvent the problem entirely, but I don't since I got in a fight with my isp regarding a wireless modem that they promised me over the phone but then cheated me of).
