I charge my phone on my laptop charger, and charge my laptop on my dock. When I want to undock my laptop, I disconnect a single cable. I have two monitors that can run off a phone or a laptop using just a USB cable (no power supply). I can even charge my MBP off a Lenovo charger without a second thought. None of this was possible prior to those "years of pain." I personally welcome our USB-C overlords.
