I bought the pink 7ft cable and really like it.  I took it to a workshop where no wireless signals were permitted (radio telescope workshop.. obvious reasons for that necessity), and everyone had ethernet cables and it was just a mess with all the cables and trying to figure out which went with which laptop, etc.  But, thanks to this distinctive cable, I didn't have to be concerned with any of those issues--or with my cable magically disappearing! (which seemed to be the fate for a few of the many, many mundane blue ones).
