> But the key reason for it is that it's a dedicated power port. That means that port is designed for that. You don't waste money allowing your laptop to be charged from any of the four USB-C ports. Like, who needs that?

USB ports have to be connected to the power system anyway because they have to power peripherals. Maybe it's got to be a slightly heavier connection to charge the computer, but I'm guessing the extra cost is minimal compared to a whole different fancy port with magnets in it and a whole different cable. Who needs it? People who don't want to carry around an extra cable everywhere.
