Apple Computer Charger

WHY IS THIS A GOOD DESIGN?


The most common point of failure for a computer charger is the connection between charger and laptop.  This connection failure not only risks damaging the charger but also the expensive laptop.  All too often a computer is plugged in and someone accidentally trips on the cord.  This could rip the plug out and break it, or it could jerk a computer off a table causing it to break upon impact with the ground.  Apple has come up with a clever way to deal with this problem.

This charger has a magnetic end that seals it to the computer, allowing a firm connection but not so firm that it can jerk the computer off a table.  If someone were to trip over this cord, it would safely disconnect from the laptop without causing damage.  Because of the magnetic seal, the charger doesn't have to penetrate very deeply into the body of the laptop, thus reducing the major source of error.
