I think the big thing with Firewire and DisplayPort, though, is that the port isn’t a rectangle. It’s flush on one size and angled on the other so that you know which way it plugs in no matter what. It being non-reversible wasn’t an issue because of that. USB, on the other hand, has the same shape whether it’s right-side-up or upside-down.
