The power cable of the new 24 inches iMac has a magnetic connector which provides a one hand operation for its connection and disconnection hence is a clinch better than the plug and unplug method of the older units which of course requires both hands. It is made in such a way that it is not easy to disconnect it but when an attempt is made to remove it, it does not take a lot of force, thereby minimizing the chances of pulling down the iMac from the desk. Further the power cable as well as the previous models is longer than before giving it more placement options.
