I think we're in a troubled phase of the transition to a truly universal port. I believe soon enough most cables and charging, bricks, and devices, will start to be more versatile and also better labeled. At this point companies are still transitioning and people still don't understand the concept so we'll either. Maybe we need something like color coding in cables, similar to the color strips in resistors. We definitely need some way to know what a cable supports after the label is long gone. With that said, I still prefer the current situation where I can charge my laptop and my phone with the same cable and charger, and the same port can be used to video out.
