She answered her own question on the cable storage, but may not have realized it, though the lesson was clearly learned. Strain relief on those wrap around chargers was always an issue.

You can see the electrical tape on the second one in response to the wear wrapping cables around the ears induced, and also the careful way she made sure to add a fair amount of free cable before wrapping it. In 20 years as a Mac technician, I can't tell you how many times I had to explain to people how they had to keep a loose loop at the start if they didn't want to have to replace their charger yet again.

Convenient yes, but I think I prefer the chargers with detachable cables that have become common.
