In many ways the USB line has replaced the MIDI serial line for most of todays MIDI work. I think this is a good thing as it means each MIDI unit has it's own port. The one thing the MIDI port has is groundloop protection, USB does not.

its own physical connection point, maybe. but USB interconnection is heavily hub dependent. and each port doesn't get its own one of those. groundloop protection for a serial data protocol?
