In all seriousness though, these are important for a non-obvious reason: Nexus 6x devices don't ship with USB2-USB3 adapters (they only have a USB3 cable with a wall charger).
So ... anyone who wants to hook up their Nexus 6x to a laptop will almost certainly to Amazon to buy a cable. This is what I did last week, and just today I discovered that certain cables do not quick charge.
Benson Leung, you are doing the lord's work. May future Nexus 6x owners benefit from your expertise.
Generally speaking, USB cables won't make the receiving end request more than they can handle. It's always about the power source.
Looking forward to laptops with USB C connectors.
Surprisingly it's been slow! I was very sad to see, for instance, that MS Surface Book does not have a USB C port. It is the single reason that I'm not going to buy the Surface Book.
At least Apple went all in with the Macbook air. Also, I think iPhone 7 will use the USB 3.1 type C port.
I know the criteria for selecting my next laptop and monitor will involve USBC.
