MagSafe power adapter

The Apple MagSafe power adapter achieved the basic goal of a power adapter of connecting my computer to power, but once I saw how it would easily pull out when someone tripped over it, I wondered why it wasn’t a standard feature of power cords for computers to come out easily. It is the kind of feature that is only created when a power cord is tested in the many places people use them rather than in nice controlled conditions. The portability of a laptop created new challenges that were never an issue with desktop computers. The MagSafe made a MacBook portable even while plugged in.
