> n 2 or 3 years, no one will be selling phones charging with Micro-USB
> In 3 years, USB-C will dominate the market,
Which is another type of fallacy, but that's besides the point -- why will they change? Because everyone wanted a different charger or because some company decided to be "brave" and "courageous" and change them?
I don't understand your question or why my statement is a fallacy. Look at the market. Android phones are clearly moving toward USB-C.
As for why? My pet theory is because the companies making phones could no longer defend the outdated and annoying Micro-USB in the face of Lightning.
In 3 years, USB-C will dominate the market, but will have only a 3-year history of backwards compatibility. Assuming Apple keeps the lightning connector for that time (and I expect they will; 30-pin had a longer lifespan than Micro-USB), they'll have a 7-year history and a far longer history of backwards compatibility than USB-C.
At some point in the future, Apple might even jump on the USB-C train for their phones. But I think it will be a while, and I don't think Apple is doing the wrong thing by their customers by waiting.
