theres are a few advantages.
1. guide #
2. sync port
and a few more...

Power. Refresh time. Ability to control other E-TTL flashes. Those are the biggies that I can think of of the top of my head.

You can add an external power supply to the 580EXII.

When 580EX II is used off camera, and it's connected to the camera by its sync port and PC cable. Will the 580 still retain the ETTL capability just as it's mounted on camera hotshoe?
Thx

Not with a PC cord.
A PC cord has two conductors and is nothing more than a means to close a circuit.
