How did so many of these corps arrive at the same decision at the same time? Possibilities:
#1. Each corp sees the same need for this.
#2. Each corp is watching the others and copying their moves.
#1 is unlikely. Dropping the headphone jack adds user expense and eats battery life for a trivial space savings.
#2 is unlikely because more corps would have broken ranks to keep the headphone jack and scoop up the segment of the market that wants one.
So, how did so many of these corps. manage to do the same thing at the same time?
