But why didn't Casio use a standard mini-USB?

Bullshit. There is too wide of a range in both voltage and current requirements. Your 'universal AC adapter' would be large and expensive, compared to the current method of selecting the proper power supply.

prove it.

There are econmoic forces that tend to make this happen when it makes sense anyway... the most popular DC adapters today seem to be 5V @ 500mA-2.5A and
12V @ an amp or so. Obviously it's not practical to have all portable electronics use the exact same power supply, but I think today just having a small handful around covers almost everything whereas 20+ years ago that wasn't the case.
To say nothing of the different battery (capacity, chemistry) charging requirements.

"The Micro-USB connectors are unique in that they feature a stainless steel shell, which yields more than 10,000 insertion cycles for longer life and higher durability, and passive latching mechanism for higher extraction forces."
I guess this now means we all have to carry both a mini-USB cable and a micro-USB cable when we travel in addition to the typically unused USB cable that we carried for the past 5 years.
I guess, over time, the mini-USB cable will be phased out but for the next five years, we need to bring two cables with us.
Still, it's a lot better than carrying two chargers!
The world will be a better place when all portable electronics use the same power supply!
