It's hard to see the logic of this. Instead of two camps (Android/usb and Apple/lightning) we'll add a third: Apple/usb. What about all the existing kit? Will Apple users need to buy new chargers for future equipment? Why can't Apple just make usb/lightning adapters available for a fee. Why can't they standardise on the other end of the cable which is normally the larger USB A? - the big one used on mains sockets. Then we'd only need different cables.
But won't we need different chargers or mains adapters for different types of equipment. Whilst 1A will be OK for phones, laptops and tablets can swallow 2A or more.
In any case, by 2024 won't we be using wireless charging? That's when standardisation should kick in.
