It'll be interesting to see how this will work with USB-C unless they're being very courageous.
That's important for Pro Display XDR users, or Thunderbolt dock users, who only use one cable to plug their Macbook in (power+thunderbolt).
Or, screw it, we end up with a charging only breakway USB-C port.
For maximum trolling they should charge $29.99 for this feature..
And if they move to the iPhone MagSafe charging puck design, I imagine they'll sell those separately.
