The mm or so makes a big difference when you’re trying to sell the latest super slim mobile.
Also, the EU is pushing standardisation to micro usb to avoid people needing multiple chargers (which then tend to be left on wasting more power).

I keep reading this, and I fail to understand how it affects Apple, or anyone else, seeing as how they can all use exactly the same wall-wart chargers, or computer or TV, because all devices have cables with a standard USB plug on the end. The only difference is the plug on the other end, which I’m pretty certain isn’t covered by the legislation.
USB C will mean that there will, at last, be a common cable as well as plug that can be eventually used across multiple devices.
The only reason people have multiple chargers is because they have multiple devices that all use cables that plug into USB ports; how could you manage to charge four or five devices overnight with only one charger?
It’s interesting that USB C looks remarkably like Apple’s Lightning connector…
