Apparently the two USB-C ports are different specs [1]
- USB 3.0 10 Gbps with DisplayPort support
- USB 2.0 480 Mbps
Both support charging but only one supports higher speeds and DisplayPort (A18 Pro limitation, as Apple probably doesn't dedicate much silicon to USB I/O).[1] https://www.macrumors.com/2026/03/04/macbook-neo-features-tw...
The USB 2.0 should be the one on the back, so the charging cable does not interfere with me plugging and unplugging things from the good port.

I'd like to run the external display plus an external SSD at USB 3 speeds, so I'd be waiting for experience reports on whether the one port can handle both without constraining the filesystem transfer speeds.
Well the costs had to be cut somewhere. At least they put a headphone jack in it, so they're doing better than Microsoft on that front (who inexplicably removed it from the SP line)
Charging in and DisplayPort out on the same socket would mean an additional dongle or hub or something, so there's at least that reason for having both.
Makes sense, the iphone has only one port after all. Interesting that it supported a second one though, or maybe that's the Pro revision designed for this use case?
